Store Gets New Products & A Makeover!
Just a short posting to announce some changes at our Little Stropper/Vintage Shaving Shoppe store. We completed (for now) our line of Premium diamond slurry sprays with the addition of the .125 SPD formula. We also added a package deal - the COMPLETE LINE of sprays PLUS a bottle of SlurryLube for 10% off the cost of the individual products! This is on top of the deep discounts you get everyday off of our competitor's prices. If you haven't been to the Store yet, please have a look around!

NEW Product Coming Later This Week & .25 PCD Off The Charts!
Sales of our .25 Micron Polycrystalline Diamond Slurry spray is exceeding all of our expectations. We are completely sold out at the moment. We have placed another order (every lot is made fresh and to our specifications) and we expect to ship more product by next Monday or Tuesday. After chatting with some of our customers, they are reporting buying this spray because, in the words of one customer "(Little Stropper) diamond sprays are SO much less expensive than competitors, it's hard to justify NOT buying a bottle." While the .25 Micron PCD spray is the largest single seller, we have had many sales of the entire line of sprays, both in the USA and worldwide.
In response to many requests for an even finer level of honing by our straight razor customers, we will also be introducing next week our .125 Micron Polycrystalline Diamond Slurry Spray. And even though this formulation costs us nearly three times what we pay for our $12.95 bottles of 1 Micron MCD slurry, we will be keeping the price of this new product low by cutting back on our own profit margins. The price of this new spray will be only $17.95 per two ounce bottle. Compare that with competitors such as the one here, selling the cheaper .25 Micron formulation for $33.95. We will NOT be undersold by any competitor. If you haven't tried your first bottle, now is a GREAT time to start.

A Hard Particle Is Good To Find: The Diamond Vs. CBN Debate
It is a truism of marketing that when a market-space starts becoming crowded with product, someone is bound to come out with something they claim to be "New & Improved" to attempt to capture greater market share. You are seeing this happen right now in the razor and knife honing market. There are quite a few products on the market, including ours, which utilize diamonds as the primary abrasive to perfect your blades. With the market becoming crowded with various brands of diamond sprays, each using different formulas and quantities of those magic microscopic gems, at least one clever vendor has come out with something new - CBN.
Actually CBN isn't exactly new. In fact, it has been around since the 1970's. But what you probably want to know is if it offers any real advantages over the tried and true diamond slurries. That is the question that this short article will answer.
It might be useful to start out with a basic knowledge of the stuff. CBN, or Cubic Boron Nitride is a laboratory manufactured material which has the same crystalline structure as diamond. It is 2nd only to diamond in hardness, which makes it harder than all known metals.
But does it have an advantage over diamond slurries? Surprisingly it has two, but there is a caveat to this statement, so please read to the end.
In situations with large amounts of friction, diamond, which is nearly 100% carbon, can form an affinity for the carbon in the steel. This can cause the diamond particles to break down and lose their effectiveness. This problem does not occur with CBN. Secondly, diamond suffers from a massive loss in hardness when it gets hot, making it effectively softer than CBN under these conditions.
Sound like a problem, doesn't it? So how hot does the material have to get to give CBN the advantage? Pretty toasty, as it turns out. The metal would have to achieve a temperature of 700 degrees Celsius (1,292 degrees Fahrenheit) for the performance of diamonds to degrade to an effectiveness below that of CBN. I don't know how many "X" strokes I can do on a hone or strop in one minute, but I believe that I have a very long way to go before I am going fast enough to generate 1,292 degrees of heat. Of course, by then my strop would have long since caught fire :-)
Yes, I have taken a moment to poke a bit of fun at the issue, but there is a serious point here. You, the consumer, are being presented with an ever-increasing array of choices. This is both a blessing and a curse. You can get some excellent values and you can also get mislead. There is no evidence to demonstrate that, all things being equal, CBN cuts faster or in any way performs better than diamond....unless you are working at those very high temperatures or very high levels of friction which create them. You needn't take my word for it; research it for yourself. Any decent article on the advantages of CBN over diamond will mention heat/friction as the primary factor in its superiority.
That said, I would expect the performance of CBN slurry spray to be no worse than that of diamond sprays - although at $32.95* per 2 oz bottle of CBN vs. $14.95 for the most expensive of our Premium Diamond Slurry Sprays, the price may give you pause.
As I have said countless times - the only way to find what work for you is to try the product. That is one of the reasons that we keep our prices affordable and you, our prospective customer, armed with the facts.

A Good "Look" At Diamond Slurry Sprays - Avoiding The Deception of Appearances
Gaining an in-depth understanding of superabrasives, including natural and synthetic diamonds, involves years of experience and education well beyond that possessed by the average reader. And it can be somewhat overwhelming to the prospective buyer when they are peppered with Scanning Electron Microscope photos and the output of the myriad other equipment used in the SA chemist's lab - all as proof that a particular seller's product is the best. One could dive deeply into this rich pool of images and data and be lost for weeks.
In this article, however, I wanted to get away from these highly technical arguments for buying these products and discuss something that anyone looking at these products can see just by looking at the bottle.
When I receive my slurries from the chemist, they are delivered in large clear glass bottles. Long ago when I first started testing slurry formulas to find the ones that were most effective, I left several of these bottles on the shelf for a couple of weeks when I went away on vacation. When I return to the untouched bottles, I found, to my horror, (particularly in the cases of the 1 and 2 micron formulations) that the liquid in the bottles was crystal clear, with just the smallest amount of off-white powder glazing the bottom! It looked to me as if there was almost no diamond at all in the formula. After all, I could see hefty piles of white powder sitting at the bottom of the bottles of my future competitor's products, so I certainly expected to see a similar amount of this magic dust in mine. As I had paid dearly for these slurries, I immediately phoned the chemist who proceeded to further my "education" on superabrasives.
As I have written before, microns are extremely tiny things. The period at the end of this sentence is 400 to 600 microns across. This makes a particle the size of one or two microns not only invisible to the naked eye, but also invisible to a powerful light microscope. In fact, an expensive Electron Microscope called an SEM is needed to see these very small abrasive particles. The chemist, who had over 20 years of experience working with superabrasives, reminded me that, given their size, these tiny particles cannot be seen by visually inspecting a bottle of them in solution. "The white powder at the bottom of the bottles you saw," he told me, "was another substance or mixture of substances. Without having a bottle of these products to inspect, I can't tell you what they are, but I CAN tell you what they aren't - diamonds." He went on to say that there were undoubtedly some diamond particles mixed in with the white stuff, but not necessarily any more than were anywhere else in the bottle.
This was an important part of my education in superabrasives and I thought I would pass it along to those of you who are thinking of buying these products. When you are considering diamond slurries, your eyes will tell you little to nothing about the contents of the bottle. The information reminded me of something that Obi Wan Kenobi said to Luke Skywalker when teaching him the ways of the Force: "Your eyes can deceive you; don't trust them." It is a good rule of thumb to follow when evaluating diamond slurries.
As I have said it many other pieces on this subject, there is one test and one test alone that counts - using the product. So if you are interested in really keen blades, I'm afraid you are going to have to buy 'em and try 'em. I recommend ours. They are up to 35% less expensive than competitive products and they work. Use the product for a full 7 days. If you aren't satisfied, return the sealed bottle containing the unused portion of the slurry and receive a FULL refund*. If you have any questions before buying, including which product(s) will work best for you, email us at info@littlestropper.com.
*Refunds made only for products returned with tamper-evident neck seal intact and no other signs of tampering. Refund offer is restricted to ONE bottle of any of our Premium Diamond Slurry Products, one time only. S&H charges cannot be refunded. Refunds will not be made to competitors buying our products for testing or to commercial buyers - in other words, you must be a legitimate consumer to qualify.

JUST RELEASED: Our NEW line of Premium Diamond Slurry Products.
Anyone who uses straight razors knows the value of a truly polished edge, which is as free as possible from imperfections and those nasty serrations. As someone who sharpens razors professionally, I know it can take a lot of time and effort to get a razor in a condition where it is fit to shave with - old wedges can be particularly troublesome. But once I'm done and have sent the shave-ready razor to a customer. I want him to be able to use it for many months without having to send it back to me for rehoning. So I took the system that I created for my own razor finishing practice and made it accessible and easy to use for the average shaver. Best of all, this system doesn't require investing in expensive hones and it doesn't require a lot of room. It is easy to use and it doesn't make a mess. It is our patent pending blade finishing system - the Magnetic StropBox and our NEW Premium Diamond Slurry Sprays..
The Magnetic StropBox System pairs up a box with one magnetic side with a two types of tops (called StropTops) that adhere to it - top bovine leather and 100% hard wool felt. Of particular interest to the razor user is the hard wool felt StropTop. These soft but tough tops are the perfect surfaces on which to use our exclusive line of Premium Diamond Slurry Sprays, available in 2 Micron 1 Micron, .50 Micron and .25 Micron. Just spray the felt lightly and strop your edge to perfection. How far you want to go down in grit is up to you. 2 Microns in the equivalent of an 11,000 grit stone. Some folks will be fine with that. I like to go all the way down to 1/4 Micron for the smoothest possible shave. It's the finish that I use for my razor customers and the one I use for myself. Of course, I finish up with leather before shaving. With my handy StropBox and StropTops, I no longer have to stand in the bathroom to strop razors. And the tops are so cheap that I don't have to kick myself if I cut one.
The system also works for pocket knives, kitchen knives and tools.
If you want to keep your razors performing at their best and your knives and tools at their sharpest, you MUST check out our products TODAY!

Diamond Slurry Sprays, Lubricity & Particle Characteristics: How To Put The Ultimate Edge On Razors, Knives & Tools
Diamond Slurry Sprays, Lubricity & Particle Characteristics:
How To Put The Ultimate Edge On Razors, Knives & Tools
By John H. Tischler
Friday, December 24, 2010
Introduction
While I’m sure that you all understand the concept of friction, many of you probably are unfamiliar with the term “lubricity.” Lubricity is defined in the Merriam-Webster dictionary as: the capacity for reducing friction. You can also think of it as the ability of a lubricant (i.e. oil, water, Teflon, etc.) to reduce friction between two objects. Just for your information, the study of lubricity is part of the larger science of Tribology – the study of interacting surfaces in relative motion. While this information may be very interesting to some and boring to others, it’s critical for anyone who wishes to truly understand blade sharpening and polishing. So if you belong to this determined group, or wish to, read on.
Lubricity & The Pursuit Of The Perfect Edge
Since the pursuit of the perfectly keen blade is our agenda here, let’s apply the principles of lubricity to the honing and stropping of fine blades. Assume we have a flat surface covered with a liquid containing particles that are harder than steel. Let us further assume that we are moving a steel blade over that surface, using just the weight of the blade itself for downward pressure. As the lubricity of the liquid increases, the friction between the abrasive surface, and the steel contacting that surface, decreases. This decrease in friction reduces the ability of the abrasive to remove metal. The degree to which an abrasive removes material is often referred to as the “cutting power” of the abrasive.
Since cutting power is what we all want from our abrasive surfaces, we should always want to keep lubricity to a minimum, right? Well, that depends. Have you ever tried honing a blade on a dry waterstone? How about on a dry DMT diamond plate? If you have, you have already experienced the effects of very low lubricity – quite a bit of metal is removed (not always where you want it to be) and the stone or plate is soon clogged with worn metal fragments. This makes the abrasive surface an inconsistent cutter – leaving some spots that will cut harshly and others where cutting power is virtually non-existent. Further, this lack of lubricity also makes for a very rough edge – something you can see under a microscope and, certainly, feel against your skin.
The Role Of Lubricants In Creating Better Edges
It is for these reasons that we generally use a lubricant (something which increases lubricity) when we are honing. Lubricants reduce the friction between the abrasive and the blade – reducing cutting power, but producing a more consistent “cut” and a smoother edge. The lubricant also helps to carry away the metal (and “spent” abrasive particles) removed by the abrasive in action, helping to prevent the “clogging” of the honing or stropping surface which occurs when the surface is too dry. Lastly, using a lubricant extends the service life of an abrasive’s surface.
Proper lubrication is most important when you are using an abrasive that is considerably harder than the piece you are attempting to sharpen or polish – and they don’t come any harder than diamond. Diamonds, natural or synthetic, are the hardest substance on earth. Hardness isn’t the same thing as toughness – you could take a hammer and easily smash an engagement ring (PLEASE don’t try this at home); it just means that, when moved against a softer material (which is everything else on earth other than another diamond) with sufficient pressure, the diamond will cut into that material and remove some of it. The depth and shape of this cut, and the amount of material removed, are all impacted by the shape of the diamond, the pressure applied to the workpiece against the diamond and, last but not least, the lubricity of the solution standing between it and the softer material.
Water is the most common and least expensive lubricant. It also has extremely low lubricity and viscosity (a measure of the resistance of a fluid under stress, often known as “thickness”) – which is one of the reasons why it’s not used to lubricate the moving parts in car and truck engines. It does, however, have qualities that are very desirable when honing a razor, fine knife or tool. It is plentiful and inexpensive, is easily cleaned up and does a fair job of carrying away worn metal and spent abrasive, ensuring a more consistent “cut” and extending the life of abrasive materials. It also aids in producing a less jagged edge than you would otherwise produce using a dry surface, although not nearly as smooth as one would get with a superior lubricant.
The Princess And The Pea – How Something Very Small Can Be Very Irritating
Even though it is the main topic of this paper, I am going to leave the subject of lubricity for a little while to talk about abrasive particles on the micron and particularly the sub-micron levels. You will have to trust me that this short diversion is important and that I will return to the topic in a few paragraphs. Firstly let us quickly try to wrap our brains around the concept of the micron-sized particle. To put microns in perspective, you may wish to consider that the period at the end of this sentence is approximately 400 microns across; and that one micron is equal to about 1/300th the diameter of a human hair strand. Sub-micron level particles are obviously even smaller – so small, in fact that Electron Microscopes are required to see them.
Despite this miniscule size, there is a common complaint about slurries which utilize diamonds smaller than one micron in size – that they leave an edge that is too harsh or “toothy.” This seems somewhat counter-intuitive when dealing with particles so tiny, but it’s true. This effect leads many honemeisters (persons skilled in the art of creating perfect edges) to use chromium oxide (a substance which is softer than diamond) pasted strops after using diamond slurry sprays to “soften” the edge. The reasoning often runs something like this: “Diamonds are a harder substance and thus will cut deeper and rougher scratches than will chromium oxide, therefore honing on chromium oxide is necessary to ‘smooth’ the edge.” This is only partially correct and is typically a result of using the wrong type of diamond in the wrong way.
Synthetic Monocrystalline Diamonds (SMD)
Most diamond slurry formulations sold for sharpening fine blades rely on synthetic monocrystalline diamonds (SMD) as the abrasive.
Popular for their extremely low cost and high durability, SMD diamond slurries are an excellent choice for earlier stage material removal, but have some inherent problems that make them a poor choice for final finishing work. These problems include, first and foremost, the shape of the particle itself. It is “blocky” with very sharp, but very few cutting edges. SMD slurries also suffer from problems with particle shape, such as the existence of needle-like “slivers” and long and flat “plate structures.” These “strays,“ which often get past even the highest quality Particle Size Distribution (PSD) testing equipment and procedures, lead to SMD’s relatively high “scratch rate” – tiny bits of damage to the blade’s sub-surface. These scratches are not visible through magnification under a normal microscope (you would need an Electron Microscope to see them), but they can be perceived on an edge that is used for shaving as “harshness.”
For these reasons, SMD diamond slurries are not the first choice of manufacturers needing to produce the finest finishes. They are also why I do not recommend the use of SMD diamonds in sub-micron level slurries used for final finishing/polishing. While it is beyond the scope of this paper to delve deeply into the subject of diamond morphology, I felt that I have to mention it I have read claims by leading competitors that monocrystalline diamonds are more appropriate for finishing because they will leave a less “toothy edge” than polycrystalline diamonds. It is well known that, in fact, the opposite is true.
Synthetic Polycrystalline Diamonds (SPD)
Synthetic polycrystalline diamonds (SPD) share many attributes of their monocrystalline cousins (particularly hardness), but their structure – formed by a controlled detonation of high explosives, is very different. Each tiny SPD particle contains even smaller “microcrystallites” whose numerous planes are pointed in different crystallographic directions every 10 to 50 nanometers (a measure significantly smaller than microns) – regardless of the particle size distribution of the parent particle. The hardness of each individual microcrystallite can be compared with that of synthetic monocrystalline diamond. Due to the greater number of cutting edges and greater surface area simultaneously contacting the workpiece, SPD-based slurries remove more metal than SMD slurries and are much less likely to cause subsurface damage to the metal ±. But all of these good qualities come at a price – with polycrystalline diamonds costing much more than monocrystalline preparations.
Lubricity Revisited
Earlier in this paper, I described the characteristic problems of using abrasives with little or no lubricant – inconsistent cutting, harsh cutting and clogging of the abrasive surface. Considering what we have learned about the “stray” particles in SMD slurries, is it any wonder that these problems would be compounded by using a solution with very low lubricity – particularly when you are using particles with an inherent tendency to “gouge?” Does scratching not worsen in an absence of lubrication?
Most diamond slurry sprays, such as the ones produced by current market leaders, use carriers (the solution in which the abrasive particles are suspended) with very low lubricity – depending primarily on de-ionized water to reduce friction. You can see this in the way these product atomize (disperse in a spray) – producing an extremely fine mist, much like tap water (A bit too fine, in my opinion. At a distance from the strop of 5”, one of these products produced a rough circle 8” in diameter – leaving more slurry on the table than on the strop. Sprayed closer, the slurry is too “concentrated” in one spot.). They also tend to dry quite quickly on a 100% hard wool felt strop – also an indication of a primary dependence on water as a lubricant. You can also feel the almost complete absence of viscosity in the “draw” or friction perceived when stropping a blade against a hard wool felt strop treated with these products. And since it they are often used dry, that friction is enhanced – at least until the abraded metal starts clogging the surface.
So after I strop a razor on hard wool felt sprayed with products of this type, used wet or dry, I do find that stropping on chromium oxide is necessary before use – as the blade coming off a strop sprayed with it does tend to leave a harsh edge. If you are working with knives, you probably want a harsher edge – especially at sub-micron levels, as the microscopic scratches may produce better cutting action – you just might want to pay less for it.
How To Get The Ultimate Edge For Less Money
We have customers all over the world looking to put the best possible edges on razors, knives and fine tools. In response to these needs, Little StropperTM has formulated products that use the less expensive synthetic monocrystalline diamonds in our 1 and 2 micron slurries (where a higher scratch rate matters less and may even be desirable), and the more costly synthetic polycrystalline diamonds (SPD) in our .50 micron and .25 micron slurries. Since the sub-micron level slurries tend to be used for finishing and polishing, we felt that using synthetic polycrystalline diamonds, with their much lower scratch rates, was worth the extra expense. Additionally In all of our formulations, we use significantly higher levels of water-soluble lubricants than you will find in the leading brands. So you will feel less friction when using our products, but you will get a better and smoother edge. You will also use less of the product, as we add special ingredients designed to keep the stropping surface moist for long periods of time.
Another thing you will appreciate is our prices. Even our SPD formulations, which utilize a much more expensive diamond than do our SMD products, are priced lower than the leading brand. Depending on the formulation used, our products ounce-for-ounce cost up to 35% less than the current market leaders. We are announcing the following products, which will be available for sale in January of 2011:
- 2.0 Micron Premium Synthetic Monocrystalline Diamond Slurry Spray (2 oz size)
- 1.0 Micron Premium Synthetic Monocrystalline Diamond Slurry Spray (2 oz size)

Beware Competitors Bearing Carats
A word to the wise – be wary of diamond slurry manufacturers that attempt to distract you from the price of their product by focusing on the number of carats of diamonds in the bottle. “Stuffing” more and more diamond powder into a bottle of slurry, while certainly providing a rationale for charging a high price, is unlikely to improve the product’s performance. The additional diamond particles just end up being wasted. Our products are formulated with a focus on performance and results – not on carat weight. So you end up paying for effectiveness, not powdered diamond.
Conclusion
I have used quite a bit of science and jargon in this paper – I do apologize for this and have tried to keep it to a minimum. But most of you reading this (and thank you for coming this far with me) are not Tribologists. You are folks who, like me, want a smooth close shave every day. You want knives that will cut cleanly without slipping. You want chisels and other bladed tools that will remove material reliably without “skipping” off surfaces or damaging your creations. You also want to spend less time and money getting there.
If any of the foregoing describes you, please try our Little StropperTM line of Premium Diamond Slurries and blade finishing products. You will find them at www.littlestropper.com/store in January 2011. If you have questions, please contact us at info@littlestropper.com.

Welcome Blog Followers!
I just wanted to take a moment, in this season where we are all rushing around, stretching both our legs and our budgets, to thank everyone who has taken the time to follow our blog.
Blogs are, by nature, somewhat narcissistic and self-serving.. They are usually written by a single individual with a particular point of view. I try to fight this urge with every keystroke and just keep writing good content that will inform, amuse or otherwise aid you in your journey into the world of wet-shaving.
I would be remiss if I made no pitch at all for our new Magnetic StropBox System. This is a device that I'm very proud of. I put each one together with my own two hands for each of you. This device is how I finish each and every shave-ready razor we sell. So if you are a fan of our razors, then you are already a fan of our system. By using it, you will keep your razor shave-ready for longer than you ever thought possible. While I was stropping the old fashioned way, I never realized just how much time I spent standing in my washroom, staring at the tiles stropping razors. In retrospect, it was a somewhat odd thing to do. Now I can sit on my back porch, look at the trees and all those leaves I have yet to rake and strop razor after razor. At under fifty bucks for the entire system, it's a damn good deal. If you would like it for the holidays, send me the email address of your "gifter" and I will drop a subtle hint in their In Box ;-)
Not wanting to let this posting end on a self-serving note, I found a FREE book that you might find amusing. It is around 150 years old and is entitled: The Life & Adventures of Henry Smith The Celebrated Razor Strop Man. Yes, there IS a book about someone who strops razors for a living. It is, as the cover of the book says, "A complete collection of his original songs, queer speeches, humorous letters, and odd, droll, strange and whimsical sayings."
Enjoy it and welcome to the blog!

Don't Strop Under Stress!
I give good advice. The problem is that sometimes I don't take it. It's 1AM and I'm stropping razors after honing up a whole bunch. That can be a very bad idea. After performing the same "blade first" motion several hundreds of times on the hones, it can be hard to switch gears and go into the "spine first" motion required for stropping. "Muscle memory" is a bitch. Unfortunately, I am quite good at honing and on one stroke I forgot to turn the razor around - needless to say I soon had an irreparable slice across my strop.
Now had I been using my traditional $65 hanging strop, I would have been quite angry with myself. Fortunately, I was using my Magnetic StropBox system with a leather StropTop. While I wasn't happy about slicing my StropTop in half, at a retail price of $19.95 (and since I manufacture them I get a bit of a discount) I can only get so upset with myself. I simply pulled off the damaged Leather StropTop and placed a new one on the box. The whole operation took about three seconds. Although afterwards, I did take a bit of a break to get my mind into stropping, rather than honing, mode. Now I am happily stropping away on my newly replaced Leather StropTop.
If you haven't already done so, why don't you take a look at the Magnetic StropBox system? It's what I use to finish and maintain the razors I send all over the world. You will still be annoyed if you cut into your Leather StropTop, but there's a whole world of difference between being $19.95 annoyed and $65 furious.

Be An "Early Adopter." Get A Sharp Edge & Support Entrepreneurship Worldwide!
I have been blogging for the last week or so about our new StropBoxTM system for maintaining the shave-ready condition of your razors and for putting the smoothest edge on your knives. Perhaps because our products are so new and unlike others on the market, some folks have been reluctant to put a toe in the water and try this new product. It’s as if everyone is waiting for someone else to go first, before they are willing to take a chance.
There is a rare breed of people known as “early adopters.” These are the men and women from every class and every part of the world who seem to be the first on their block to try something new. While they risk being disappointed with what they find, they do seem to be just a little happier and a little more interesting than other folks.
“We live”, as old Chinese curse says, “in interesting times.” Many of us are reluctant to take chances due to the bad economy, high unemployment, terrorism, global warming – the list goes on, but I’m sure you get the point. There are those who, through their crafty use of statistics, rhetoric and threats, seek to keep us afraid and off of the frontiers that will lead us to success and independence.
But there are people out there, people like me and perhaps like you that are willing to take chances…to try something different even at the risk of failure. It is a trait that has usually been ascribed to Americans – such legends as Thomas Edison, Bill Gates and Amelia Earhart; but I believe that this quality is a part of every culture and every walk of life all over the world. I bet that you personally have some great ideas rattling around in your brain dying for attention.
I made the choice to invest my time, considerable money and some ego at a time when I was low on all three, to take an idea and bring it to life. What to you looks like a newfangled idea for maintaining your razor is, for me, a chance to bring something new into the world. To build a business; to put people back to work; and to prove that innovation and guts are alive, not just in America and not just among those wealthy few with research labs – but on the kitchen tables and in the basements of average homes.
When you buy a StropBoxTM or any of our Little StropperTM products, you are supporting innovation in a nervous world. I love being a part of that and I invite you to join me.
I recently learned about a unique enterprise called Kiva.org. You may have heard of it, as it was featured on Oprah Winfrey’s List of Favorite Things of 2010. Kiva provides funds to institutions that make “micro-loans” (small loans) to some of the poorest people around the world who are trying to lift themselves up out of poverty through entrepreneurship. $125 may not seem like a lot to you and me, but in countries like the Philippines, Haiti or The Congo, that money can go a long way towards helping an entrepreneur start or build a business. It can employ people who are starving, and allow them to provide food for their families and dignity for themselves. Many of the business that receive these small loans fail, but others succeed - providing jobs and hope for entire communities in places where hope is all but dead.
So I issue you a challenge: Buy any Little StropperTM product from The Vintage Shaving Shoppe, LLC. between now and December 31st and I will take 10% of the price you pay for the product – NOT 10% of the profit, 10% of the price YOU PAY for ALL Little StropperTM products, pool it together with that of other “early adopters” like yourself and use that money to make micro-loans to businesses through kiva.org. I will even keep you posted on our blog, tracking the total amount collected and the total amount invested. Any monies that we loan that are repaid, will be re-invested in other businesses. Not one dime will go into my pocket. You and your fellow “early adopters” can be part of something big, by buying something small. To get the ball rolling, I have invested $25 of my own money in a loan to a young man in Colombia who is trying to expand his manufacturing business. Should this loan be repaid, the money will become part of the pool which will be built up by your purchases of our products.
Currently, Little StropperTM products, especially the Magnetic StropBoxTM and StropTopsTM can be purchased on eBay by clicking here. We should have our dedicated website up and running shortly, at which point we will transition to selling there.
Be a part of something bold. Buy one of our Little StropperTM products today!

New Product Launch! Read Carefully For FREE Offer!
Dear Client,
This has been a very exciting week at The Vintage Shaving Shoppe! Now that we have finally filed for our patent, we can let the "cat out of the bag" on the newest and most innovative product available for maintaining your straight razors and fine knives. The Magnetic StropBoxTM along with our Magnetic StropTopsTM, part of our Little StropperTM brand, provide a low cost, easy to use system for keeping your blades shave-ready longer than ever. And you will never have to look for a place to hang a strop again! For a long time, I have been telling my customers about the benefits of stropping on surfaces with varying degrees of abrasiveness. But that used to mean having a whole bunch of strops hanging in the bathroom – not a wife-pleaser. It’s also a very expensive way to maintain your razors, with strops running $30 to $70 each.
Those days are over.
Using the power of flexible magnets, the Patent Pending Magnetic StropBoxTM and Magnetic StropTopsTM create a completely swappable straight razor, knife and tool maintenance system that can be carried and used anywhere! And since the 8.25” X 2.5” X 2.0” Magnetic StropBoxTM unit has a sliding door on the bottom of the unit, it’s perfect for storing a razor, a shaving brush, a barber’s hone or a small tube of abrasive paste – if it fits, it is secure inside the Magnetic StropBoxTM. And the system couldn’t be easier to use! The top of the Magnetic StropBoxTM is covered with a vinyl magnet, similar to the kind you might find on your refrigerator. Just apply an 8.25” X 2.5” Magnetic StropTopTM available in fine stropping leather and 100% hard wool felt, to the top of the box and you are ready to strop. And since each Magnetic StropTopTM also comes adhered to a flexible magnet, changing from one Magnetic StropTopTM to another is as easy as putting a magnet on your refrigerator door (in fact, it’s a handy place to keep them)! Hard wool felt is the PERFECT surface to use with abrasive pastes and sprays, so buy one leather Magnetic StropTopTM for final finishing and several hard wool felt Magnetic StropTopsTM pasted with different abrasives, for a COMPLETE system to keep your straight razors, knives and tools at their best. You can apply these abrasives yourself or we can do it for you. It is the IDEAL system for touching up that razor that seems a bit dull.
FREE OFFER: FOR A LIMITED TIME, WE ARE OFFERING OUR CLIENTS FREE PASTING OR SPRAYING OF THE STROPTOPSTM IN DEGREES OF ABRASIVENESS FROM 2 MICRON TO .25 MICRON. JUST PLACE YOUR ORDER AND SEND US AN EMAIL AS ASSISTANCE@ VINTAGESHAVINGSHOPPE.COM INDICATING THE STROPTOPSTM YOU WANT TREATED AND WHAT GRIT YOU WISH US TO USE. WE HAVE 2 MICRON, 1.5 MICRON, 1 MICRON, .50 MICRON AND .25 MICRON DIAMOND SPRAY.

The "Little Stropper" Is Coming To Town!
Another of those "looks" from the wife again.
Those of you gentlemen who are married or have similar long-term entanglements, are familiar with the glare that only people together for many years can share. In my case, this particular look is reserved for those days when the postman brings another brown box to our doorstep. She knows that it is even money that the box contains some manner of sharpening device - a hone, a strop, stropping paste, hard wool felt, strop conditioner, balsa wool (yes, you can sharpen on this too), a slurry stone, diamond spray or something even more exotic. And it's always the same question: "Aren't those damn razors sharp enough for you yet?" My stock answer, "not if I can get an even BETTER shave out of them." It never seems to satisfy her.
If you are a true connoisseur of the straight razor shave, you understand exactly what I'm talking about. You also probably know that it isn't all that difficult to get a hair-cutting edge on your razor - this can be done with honing stones (although the cost of purchasing all of the required hones can be prohibitive for the average gentleman. But a sharp edge doesn't guarantee you a comfortable shave - for that you need to properly strop your razor. To most people, a strop is just a leather strap hanging in their bathrooms; from a hook, towel bar, or whatever else is handy. But there is more to stropping than running your razor over that piece of hanging leather. And it was from this simple idea that Little Stropper was born. Little Stropper products:
Little Stropper is an exclusive brand of Vintage Shaving Shoppe, LLC. We will not be selling Little Stropper products anywhere except from our dedicated website, littlestropper.com, or from vintageshavingshoppe.com. The dedicated website is already up and running. However, products are not yet available for sale there yet, but you can expect them to be available in the next week or two. You can check the littlestropper.com website periodically. You will also be notified automatically when products are available if you are a Follower on our blog or a Fan on our Facebook page.
I am very excited about our Little Stropper product line because I know that every one of our products will bring you a closer, more convenient and more enjoyable shaving experience. If you have any questions, please feel free to contact us at assistance@vintageshavingshoppe.com.
Here is a "sneak preview" of two of our products...
The StropBrick: A hefty chunk of solid wood (Rosewood, in this photo) with three 6" stropping surfaces - one plain strip of bridle leather a shade over 1" wide, and two bridle leather strips 5/8" wide each treated with with a lightly abrasive stropping paste. It is perfect for traveling or simply keeping on the bathroom shelf. It's always ready to use and each one is a work of art. Clear rubber "feet" keep the StropBrick level and secure if you wish to use it on a hard surface. Personally, I prefer to hold it in my hand.
The StropBox: If you travel, or if you are simply short on space for your shaving items, you will appreciate this ingenious tonsorial item. Part high-quality vegetable-tanned leather strop and part storage case, the StropBox will keep your cutting edge smooth and provide storage for your favorite razor and anything else you can fit inside. A sliding panel secures the contents. I always grab my StropBox whenever I travel overnight and keep a tube of strop paste and a small barber's hone inside. Since the sliding panel is practically invisible, it is also a great place to keep some extra cash, jewelry, etc. on your trip.The StropBox is 100% solid wood (not plywood or pressboard) which has been hand-stained and features two coats of polyurethane on the external wood surfaces to water resistance and durability. The stropping surface is a generous 8 1/4" long by 2 1/2" wide with leather hand-selected to have the smoothness and "draw" needed to tame the edge of your razor. You may use stropping paste with your StropBox or we can paste it for you for a small additional charge.
