Cubic Boron Nitride (CBN) is a high-tech superabrasive that is second in hardness only to diamond. Offering greater abrasion resistance and thermal conductivity than conventional abrasives such as silicon carbide and aluminum oxide, CBN removes steel quickly and efficiently. Spyderco's new 3x8 bench stone combines the many benefits of CBN with a classic flat stone format to power traditional sharpening technique.
