Spyderco CBN Sharpening Stone
Grit: FINE 400 grit / EXTRA FINE 800 grit
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 like silicon carbide and aluminum oxide, CBN removes steel quickly and efficiently. Spyderco's new 3x8 bench stone combines the many advantages of CBN with a classic flat stone format to supercharge traditional sharpening technique.
The broad, perfectly flat carbon steel embryo of this stone is coated with fast-cutting FINE 400-mesh CBN on one side and EXTRA FINE 800-mesh CBN on the other. Ideal for putting an edge on knives, this stone is also the perfect choice for sharpening wood chisels, plane irons, and similar tools and comes complete with a high quality suede protective case.
