CBN offers excellent performance in sharpening knives of any steel. Due to its high resistance specs, CBN can be used dry without lubricant. This makes CBN the cleanest of the available sharpening stones. How to use KME CBN emulsions are extremely simple to apply and use too. No heating or softening required. No need to work the compound into the strop either. Just apply a single drop to the surface of the strop, spread it out evenly, and let it dry while you sharpen your knife with the stones. Each bottle contains approximately 120 drops and each drop will micro-hone at least 3 knives. That’s about 360 knives minimum per bottle. (That’s a lifetime supply for most of us!)

I have a Nikon microscope with variable power and several eyepieces that gives 10x-80x magnification. This is not the fingernail or finger print test.

The 4 micron CBN emulsion used in conjunction with one of our new Kangaroo leather strops is quite possibly the single most impressive sharpening accessory we’ve ever used and every single person who’s tried it agrees. One kangaroo strop and one bottle of 4 micron CBN emulsion are “must have” items! CBN's qualities include high levels of high hardness, strength, abrasion resistance, and thermal and chemical resistance. These characteristics exceed the values of synthetic diamonds and conventional abrasives such as silicon carbide and aluminum oxide. In particular, CBN's high thermal stability and chemical resistance make it suitable for sharpening in conditions where synthetic diamonds are not normally employed. Sharpening to a burr is counterproductive and works against sharpness. Most ceramic waterstones (1200 grit or below) have no trouble with many common 'supersteels' as the vast steel matrix around the carbides is soft comparatively and thus, easily cut by these ceramics. The Sharpmaker and Spyderco ceramic bench stones are excellent and I have used them for almost 30 years. Be careful not to press to hard and use too long or you will easily form a tough small burr, then complain it does not work very well on the newest tool steels. The problem with them being soldered in place is that when you are sharpening the diamond's are so hard they dig and hook into the steel and get torn out when you sharpen and then you do not have many diamonds left on the diamond stone.Where as with Metallic Bonding the CBN stone's I have the CBN particle's are better anchored in and are much harder to tear out.

That is interesting but perhaps you could share more information and someone aside from Cliff may have some insight? All I can say is these stones should be called for a brand name Rabid Piranha's because that's the best way I can describe them and to call them just Piranha's would not do justice as to how fast they cut.

Sharpening stones can be divided into two categories. Natural sharpening stones and synthetic sharpening stones. Natural sharpening stones are just that, natural stones. These stones were taken from a quarry. Synthetic sharpening stones can be comprised of different materials. The synthetic materials used most often for sharpening stones are ceramics and diamond. Of course each material has its pros and cons. Natural sharpening stones I honestly don't think it will matter either way when your talking about diamond or CBN,I think the problem is most people still refer to diamonds as the go to thing because they have been around for so long. CBN sounds like a wonderful abrasive that is far better than anything else on the market. So what’s the catch?

See Table Below*** For I look at it this way do these cost more yes but will the last longer then a DMT or Gold Series stone oh yes much much longer and I also get the added benefit that they cut way faster than anything else I have ever used.

The best way I can describe how the 50 grit Metallic Bonded CBN stone worked is to say that it just cut's threw S110v like it's nothing just plain and simply put it's easier then taking candy from a tied up baby,the grit also produced filing's that looked like long metal hairs that look like they were made by a power tool then a sharpening stone,the rest of the grit's also removed metal very very fast and all I can say is that you can sharpen S110v much much faster then with any other stones that I have tried and the only ones that come close are the Venev Industrial diamond stones and they are slouch either when it comes to sharpening S110v or any steel for that matter.I also stropped the edge with Poltava CBN Paste and I started with 10,7,3,1,.5,.25 Micron and I used Kangaroo leather strop's on my K02 that I made myself. CBN offers excellent performance in sharpening knives of any steel. Due to its high resistance specs, CBN can be used dry without lubricant. This makes CBN the cleanest of the available sharpening stones. Metallic CBN stones may have tone imperfections. Metallic CBN may become darker over time due to natural metal oxidizing, it does not affect the sharpening. This is where the fixed abrasives are a god-send as you can trivially bring knives to very high sharpness with even coarse plates such as the Spyderco CBN assuming you use 1- lubricant, 2 - light pressure, - edge forward strokes at slightly higher angle to grind a micro bevel, 3 - alternating strokes from one side to other/ crossing scratch patterns. All of this will tend to avoid forming a burr when actually directly grinding on the apex.
