CBN (Cubic Boron Nitride) is the second hardest material after diamond. CBN’s qualities include its high levels of high hardness, strength, abrasion resistance, and thermal and chemical resistance. In particular, CBN’s high thermal stability and chemical resistance make it suitable for sharpening in conditions where synthetic diamonds are not normally employed.
