Special heat treatment with quenching at the temperature of 1050°C and after that cooling treatment below -73°C provide high hardness, durability and enhance further sharpness.
Fitted with a ferrule and is sanitary.
Distinguished in corrosion resistance making use of compressed laminated black wood.
The indentations reduce the surface area of the blade that comes into contact with the food, decreases the food resistance and improves sharpness.
