Explosive Steel

This technique was developed from a forbidden technique that Kaimetsu illegally learned from Iwagakure. By using the technique's ability to knead chakra into objects through the mouths in the palms of his hands, Kaimetsu can infuse liquid metal with explosion release. He then moulds it into a shape, using the Kinzoku Clan's technique, depending on the abilities he wants it to have and spits it out. After moulding the steel, and compressing it, Kaimetsu can enlarge it to various sizes depending on the intended purpose of the steel. Once enlarged, the steel creations can be brought to life and controlled remotely by Kaimetsu alone, who can then detonate the clay by performing the seal of confrontation.

Kaimetsu copied this type of fighting style from Deidara, but mentioned that his version was far superior as it has "no weaknesses" - of course referring its resistance to lightning release techniques that Deidara's explosive clay was weak to.
