Steel Release (Kōton)

The Steel Release (鋼遁, Kōton) is an advanced nature kekkei genkai that can be used to make one's body virtually indestructible by turning it into black steel. It is unknown what elements this nature entails.

Uzuhashi Steel Release (Kōton no Uzuhashi)

The Steel Release (鋼遁, Kōton; Vis "Metal Style" or "Steel Style") of the Uzuhashi clan is considered to be an advanced nature kekkei tōta that usually combines earth and lightning-based chakra to create metal armour out of earth. One of the advanced forms of this steel release is the Uzuhashi clan's Kekkei Genkai, Kinzoku Hogosha, which allows the user to create metal using their bones as a shape and using the iron in their blood to turn them into steel. The most advanced form of the Steel Release is said to only have been used by Uzuhashi clan's ancestor, Kinzoku Uzuhashi, which is a combination of both Steel Release, Kinzoku Hogosha, and Yang Chakra, to form the legendary sword and armour of the Uzuhashi Clan, Sword of Shinigami and Armour of Kami. Said armour and sword is rumoured to have been used to fight against Biju's during the Shodaime Hokage's time.
