Ken's .1 Micron CBN Spray. I have sold this product and others in the series to several customers of mine already, who are in love with this stuff as much as I am. It is the finest grit of CBN available in the finest preparation available, using the highest quality standards. The formulations have been custom blended to my specifications. In addition to eighth micron, I also have it (in ascending order) in quarter micron, half micron, three quarter micron and 1.5 micron or 64,000, 32,000, 24,000 and 12,000 grit, respectively.
CBN is the next hardest material to diamond, yet in hand and high speed operations, it cuts even faster. (In high speed grinding operations, it is actually harder than diamonds - just FYI). CBN products are often more expensive than diamond in specific applications. It is particularly effective for hard knife steels over 60 HRC (Rockwell hardness), although it is quite respectable with softer steels too. It does a wonderful job on leather, balsa, paper and felt - tested in both freehand and on precision guided devices too. I have personally tested these compounds on multiple Japanese knives, scissors, etc and gotten excellent feedback on the edges (otherwise known as repeat customers). It is friable, like polycrystaline diamond too and gives prolonged cutting action.
After a good progression of stones and some 0.50 and/or 0.25Ķ diamond compound,this product on a balsa wood strop will add an extra level of sharpness you just didn’t think was possible.
My goto finisher when I sharpen a fine knife & really want to create the best edge possible!
As the previous reviewer stated,this product on balsa wood will give you a nice surprise! I can only describe the edge as feeling "extra crisp" when brushed along your thumb. This is by far my favorite way to finish a high quality steel! And,like all of Ken’s sprays,this stuff never settles. I don’t know how it stays mixed at all times,it’s magic!

A first I didnít really believe that this spray would work as well a some of the reviewers have stated. After using it...I have to agree. I was so amazed how much sharper it made my straight razors after a honing on an 8K grit stone. I did find that you only need a FEW sprays on the 3"x11" balsa wood sold here. After stropping my first razor I added a few more sprays to strop my second razor and the second razor was not as sharp as the first. I had to sand the balsa wood down and reapply the FEW sprays as I did on the first razor and there was that amazing keenness I saw on the first razor. If you apply too much you will not get maximum effect from this spray. I actually donít use my leather strop nearly as much after using this spray. Iím totally amazed.

This is part of my sharpening routine now. If blade needs correcting,I use 1000,6,000,10000,.5m on balsa,.1m on balsa. This takes it from chipped to push-cut sharp.

Update review: I have used this spray on the Nano-Cloth and got better results than with the balsa wood on my straight razors. Don’t get me wrong,this spray on balsa will give you a scary sharp edge. I just feel that the edge on the Nano cloth is more polished and gets you there faster than the balsa. If using it on the Nano let this spray dry COMPLETELY before stropping a razor on it. Amazing product !!

Kens’ 0.1 micron CBN is a quality product,especially when used with Kangaroo or Nanocloth strops. I use mine on Roo,and use it as part of a stropping progression typically following the 0.125 Micron CBN. Even at this level of refinement you can still notice a difference between this and the "coarser" sprays. In my opinion these are far superior to Chromium Oxide or other stropping compounds. This is a must have for those looking to play with the 0.050,the 0.025 micron diamond products. This is typically a finisher for me on my pocket knives. But on a quality kitchen knife this type of edge will serve a person well.
The CBN can tackle any modern steel,and plays well with simpler carbon steels as well.
