This 0.50 micron spray is 32,000 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 polycrystaline diamond too and gives prolonged cutting action.
I ordered some of the .5 cbn from Ken before it was available here. I wasn’t sure what to expect,but this product is now at the top of my list of honing compounds. I use it on a leather strop right after 1 micron boron carbide,and this finishing combination is the best I’ve found so far. I’ll be ordering the .25 micron cbn next!

Great spray on balsa after a 10k stone,getting the blade ready for the .1m spray. I used the 60x lens to view the edge and it takes a mirror-like shine using this plus the .1m as finishing.

Kens’ 0.5 micron CBN is an excellent product,especially when used in conjuction with Kanagaroo or Nanocloth strops. I use mine on Roo,and typically I use this as a finisher off of a 15k shapton pro edge. Its a versatile spray and can be used outside stropping.
The CBN can tackle any modern steel,and plays well with simpler carbon steels as well.
