The Spyderco Tri-Angle CBN Medium Sharpening Rods (brand part no. 204M1) bring a superabrasive edge 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, which is why it is a preferred choice in advanced industrial grinding applications. These CBN-coated rods combine that fast-cutting advantage with the convenience and ease of use of the standard Sharpmaker base and fixtures.
