Sharpen the blade by means of a grindstone so as to keep sharpness long.
For easy re-grinding, the blade base is wet-honed with coarse / medium grindstone by skilled craftsmen prior to formation of the primary blade.
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.
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.
Handle:Made of anti-microbial compressed laminated black wood
