Spyderco CBN Cubic Boron Nitride Sharpener 306CBN

Spyderco CBN Cubic Boron Nitride Sharpener 306CBN

Cubic boron nitride (CBN) is a high-tech super abrasive that ranks second only to diamond in hardness. CBN offers greater wear resistance and thermal conductivity than conventional abrasives such as silicon carbide and aluminum oxide, and removes steel quickly and efficiently. Spyderco’s 3x8 Benchstone combines many of the advantages of CBN with the classic flat stone format that complements traditional sharpening techniques. The wide, perfectly flat carbon steel base of this stone is coated with fast-cutting 400 mesh CBN on one side and finer 800 mesh CBN on the other. This stone is ideal for putting an edge on knives and is also a perfect choice for sharpening wood chisels, hand planes, and similar tools, and it comes with a high-quality suede protective case.
