Along with a secret forging agent, steel is placed on ground iron and heated in a furnace at 1200 degrees Celsius.
*Heating steel in high heat on the verge of melting is called “wakashi” in welding terminology and “Tsumiwakashi” refers to the process of smoothing Tamahagane, roundish steel pieces, into a single piece with a uniform surface.
The steel is hammered and forged at once, during which process impurities are scattered as sparks are released to result in a high level of purity.
*Forging refers to the hammering of hot steel.
A belt hammer is used to carefully shape the form of the knife.
Distortions generated during cooling is forged with a tool such as a mallet to straighten the blade.
Sharpening the blade
Running water is used to cool the body to prevent frictional heat from causing the blade to soften as the tip is polished until sharp.
