Profile ™ Stone CBN
This ProFile stone consists of a steel “embryo” coated with particles of 400-mesh Cubic Boron Nitride (CBN)—a state-of-the-art superabrasive that is second in hardness only to diamond. It removes steel very aggressively and is ideal for reprofiling edges and as a first step in sharpening very dull cutting tools. Suede pouch included. Eight inches long.
