Hapstone Premium CBN is a new series of CBN stones for sharpening knives using guided knife sharpeners (Hapstone, TSPROF, and other Edge Pro-compatible sharpening systems). Hapstone Premium CBN utilizes advanced hybrid metal-polymer binder - composite of traditional copper-tin alloy and polymer components. Hybrid binder inherits exceptional wear resistance and cutting performance of metallic binder.
Narrow stones (12 mm wide) are suitable for recurved blades.
CBN (Cubic Boron Nitride) is the second-hardest material after diamond. Hapstone Premium CBN consists of a 3 mm thick CBN-bearing layer mounted on a premium black aluminum blank.
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.
