Tamahagane

Tamahagane (玉鋼) is a type of steel made in the Japanese tradition. The word tama means 'precious', and the word hagane means 'steel'. Tamahagane is used to make Japanese swords, daggers, knives, and other kinds of tools.

The carbon content of the majority of analyzed Japanese swords historically lies between a mass of 0.5–0.7%; however, the range extends up to 1.5%.
