I have never used a CBN grinder. Years ago I bought a cats claw and I'am well pleased, it is a very versatile machine especially for me as I will sharpen for hire. The blue and ruby ceramic wheels sold by Cooks seem to last forever and dressing is no chore especially if you use a diamond dresser. basically you just radius the sharp corners more so on the right side. I set hook angle at 6 degrees use the same wheel profile and the same cam for everything even customers, never had one complaint. If your teeth are set right and tooth tips are sharp the band will cut. It would sure be easier to build a sharpener using a CBN wheel. Frank C.
