This 0.25 micron spray is 64,000 grit. CBN is the next hardest thing to diamond, but the cutting action is quicker and it gives me incredibly sharp edges.

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 preparation available, using the highest quality standards. The formulations have been custom blended to my specifications. I also have it (in ascending order) in eighth micron, quarter micron, half micron, three quarter micron and 1.5 micron or 128,000, 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 polycrystalline diamond too and gives prolonged cutting action.

Kens' 0.25micron CBN is a quality product , especially when used with Kanagaroo or Nanocloth Strops. I use mine with Roo , and typically I use this to follow up a 30k shapton edge. This produces an astounding edge , that few people will have ever experienced. It cuts fast , and is versatile , with applications outside of stropping.

The CBN can tackle any modern steel , and plays well with simpler carbon steels as well.

Worth every penny!
