Tamahagane (玉鋼) is a type of steel made in the Japanese tradition. The word tama means 'precious', and the word hagane means 'steel'.^[1] 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%.^[2][3]
