Tri-Angle Stone

CBN Sharpmaker Rod Upgrade

The Spyderco Tri-Angle Stone features Cubic Boron Nitride which is a superabrasive second in hardness only to diamond. It delivers greater abrasion resistance and thermal conductivity than conventional abrasives such as silicon carbide and aluminum oxide. These CBN coated Sharpmaker rods combine fast cutting performance with the convenience and ease of use of the Tri-Angle Sharpmaker system.

• Cubic Boron Nitride superabrasive construction
• Second in hardness only to diamond
• Higher abrasion resistance than conventional abrasives
