Spyderco Sharpener Tri-Angle Cubic Boron Nitride

The Spyderco Superabrasive Cubic Boron Nitride Tri-Angle Sharpening Stone Rod is a superabrasive that is second in hardness only to diamond. The set includes two sharpening tri-angle stone rods in silver color. This cubic boron nitride triangle stone offers greater abrasion resistance and thermal conductivity than conventional abrasives like silicon carbide and aluminum oxide. It is a preferred abrasive in most advanced industrial grinding application. Each cubic boron nitride stone rod measures 7-inch in length with 0.5-inch in breadth. It is easy to combine the advantages of this fast-cutting abrasive with the convenience of Spyderco’s Tri-Angle Sharpmaker which is sold separately.
