Iron Sand

, is the weapon used by the Third Kazekage, in combination with his special ability to convert chakra into magnetic forces. When imitating the sand techniques of Shukaku's jinchūriki, he used iron powder instead, thanks to his special magnetic powers. He often moulded the iron powder into weapons and used them as his main mode of attack.

When used in sufficient quantities, this iron powder can be equipped into a diverse number of ways, in which Sasori took full advantage of through the use of his puppet of the Third Kazekage. In order to create useful techniques ranging from large structures to bullet-like particles and multiple striking branches.

The Iron Sand can also clot up the joints of puppets, making them unusable in battle as long as the Third Kazekage's magnetic field is in effect, even bypassing a Chakra Shield. Chiyo referred to this technique as the most feared weapon in the history of Sunagakure. After Sasori turned the Third Kazekage into a human puppet, he too became a user of the Iron Sand.
