The Spyderco Tri-Angle CBN Ultra-Fine Sharpening Rods (brand part no. 204UF1) bring a superabrasive polishing stage to Spyderco‘s Tri-Angle Sharpmaker system. Cubic Boron Nitride (CBN) is second in hardness only to diamond, offering greater abrasion resistance and thermal conductivity than conventional abrasives like silicon carbide and aluminum oxide. In this ultra-fine grit, the CBN coating is ideal for the final polishing pass after coarser sharpening, and it combines that superabrasive edge with the convenience of the standard Sharpmaker base and fixtures.
