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-ang le 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. Show more
