The Soshu-Kitae blade, which means that the actual forging process used steel grades of different hardness, rather than the same grade as you often see online.
Soshu-Kitae is one of the most sophisticated blade constructions and is considered to be of exceptional quality work.
The hardness of this sword core is 40-42 HRC. The sides, back, and cutting edge of the blade have a hardness of 58-60 HRC. The layers between the core and the side have a hardness of 50-52 HRC. The steel was folded 12 times and the blade was treated by hardening the clay. Only the highest quality materials were used for this sword, all fittings made of metal.

This sword is hardened with clay, it is a differential blade hardening method and the most common steel hardening method. The uncured blade is coated with a mixture of clay, water, charcoal ash and finely ground sandstone. The cutting edge of the sword is very thinly coated with this clay mixture, and the rest of the blade is thickly coated.
While the clay coating mixture is being applied, the blade is reheated to a temperature of approximately 800-900 ° C. It is then cooled abruptly. Due to the thinner coating of the clay layer on the cutting side, this area cools faster than the rest of the blade. Rapid cooling changes the structure of the previously heated metal. At the same time, the cutting edge creates more hardness than the rest of the sword.
