Cubic Boron Nitride Triangle, Set / 400 grit
Cubic Boron Nitride (CBN) is a super abrasive that is second in hardness only to diamond. Offering superior abrasion resistance and thermal conductivity compared to conventional abrasives like silicon carbide and aluminum oxide, CBN makes it the preferred abrasive in many advanced industrial grinding applications. Now you can combine the advantages of this fast-cutting abrasive with the convenience and ease of use of Spyderco’s Tri-Angle Sharpmaker with these 400 grit CBN-coated Sharpmaker rods. 204MF Sharpmaker sold separately.
