Iwagakure Kinjutsu

This technique allows the user to knead chakra into materials like clay. It is a kinjutsu passed down in Iwagakure. It was originally made just for infusing chakra into objects but Deidara just uses it with clay.

Once, Deidara stole this technique in his quest to find the ultimate art. He used it to create his Exploding Clay. It is likely that the mouths on his palms and chest are a direct result of using this technique.
