The Spyderco Gauntlet™ CBN rods are for very dull knives or to re-profile worn edges. Cubic Boron Nitride (CBN) is a super-abrasive that is second in hardness only to diamond. It offers greater abrasion resistance and thermal conductivity than conventional abrasives like silicon carbide and aluminum oxide, making it the preferred abrasive in many advanced industrial grinding applications. Now you can combine the advantages of this fast-cutting abrasive with the convenience and ease of use of the Gauntlet sharpener with these CBN rods. Sold as a pair. Spyderco Gauntlet sold separately.
