Introducing a new line of resin bond diamond stones for knife sharpening. They are the culmination of 16 years of making them in many different formats, with many different abrasives, both driven up to 6000 rpm on a CNC machine in production and used by hand. While these exact shapes are new the construction and diamond/resin matrix is very well proven. These stones virtually don't wear with proper use and are easy to dress when needed. Since they don't break down themselves while sharpening the only mess is the water and swarf from your knife. The downside is after you get used to this you won't want to use your other stones.


We CNC machine the bodies from 6061-T6 bar stock then mold the diamond/resin matrix to them for the best accuracy and stability. We put as much high quality diamond in these stones as is feasible. Any more does not improve their cutting performance but does increase the rate of wear. We only use diamond, no other abrasives or fillers. The aluminum and resin is made in the U.S. and the diamond is processed here from foreign feed stock. We do all the work ourselves so these truly are American made.
