Kohetsu HAP40 Western Honesuki 150mm

The alloy used is for this lovely honesuki is HAP40. This semi-stainless steel is forged to a very hard 65 Rockwell. HAP40 is one of the hardest steels available for knife-making and it provides fantastic edge retention. It also polishes to a razor’s edge fairly easily, especially considering its hardness. It holds an edge better than almost anything else we sell. It is a semi-stainless alloy which is then clad in a full stainless steel outer layer, so it's also easy to care for.

This HAP40 Western Honesuki is a poultry boning knife. The shape is specific to that task: pointed tip, triangle shape, and fairly thick and robust. This example is double bevel as opposed to many others that are single bevel, and thus more difficult to sharpen. Do remember that they are boning knives and are not intended to cleave bones like a cleaver or deba.

The blade is coupled to a fine looking western style handle with scales made from rosewood and attached with 3 stainless rivets.
