CBN (Cubic Boron Nitride) is the second-hardest material after diamond.
CBN’s qualities include high levels of high hardness, strength, abrasion resistance, and thermal and chemical resistance. These characteristics exceed the values of synthetic diamonds and conventional abrasives such as silicon carbide and aluminum oxide. In particular, CBN’s high thermal stability and chemical resistance make it suitable for sharpening in conditions where synthetic diamonds are not normally employed.
CBN offers excellent performance in sharpening knives of any steel. Due to its high resistance specs, CBN can be used dry without lubricant. This makes CBN the cleanest of the available sharpening stones.
CBN Sharpening Stones consists of a 2 mm thick CBN-bearing plate mounted on a high-quality aluminum blank. The CBN-bearing plate contains evenly distributed CBN grains with resin bonding.
