Iwagakure Kinjutsu

This is an unnamed kinjutsu which was passed down through generations in Iwagakure.

Overview
This technique allows the user to knead chakra into materials. By doing so the object can be shaped, animated, and controlled remotely. On command, the objects size can also be manipulated — from nano-sized to gigantic heights.

Once the user infuses their chakra into an object, it can become a source of origin for a technique. Deidara stole this technique in his quest to find the ultimate art and used it in conjunction with his Explosion Release kekkei genkai to infuse explosive chakra into clay, creating his signature Explosive Clay. Sekiei, a fabrication, was given both the nature transformation and this technique to utilise it in the same way.

Trivia

 * It is likely that the mouths on Deidara's palms and chest are the result of using this technique, though Sekiei doesn't seem to possess them.
