HAP40

HAP40 is a semi-rustproof steel type (Powdered High Speed Steel) with an extremely high tool life (time that the knife stays sharp). This very special steel is expected to become very popular, because of the perfect ratio between cutting time, hardness and flexibility.

This steel is produced by Hitachi and contains high levels of tungsten, molybdenum, vanadium and cobalt. The steel in kitchen knives is hardened to 65 HRc so that it can be pushed to very high performance.
