Cubic Boron Nitride (CBN) is 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 aluminium 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 Spyderco’s Tri-Angle Sharpmaker (not included) with these CBN-coated Sharpmaker™ rods.
Sold as a pair. 7” X 0.5” (178mm X 13mm)
