This kinjutsu, which was passed down through generations in Iwagakure, allows the user to knead chakra into materials. It is likely that the mouths on the user's palms and chest are the result of using this technique.

Deidara stole this technique in his quest to find the ultimate art and used it in conjunction with his Explosion Release to infuse explosive chakra into clay, creating his signature Explosive Clay.
