Iron Sand

is the most feared weapon in the history of Sunagakure, which was developed by the Third Kazekage.

Overview
After studying the sand manipulation abilities of Shukaku's jinchūriki, the Third Kazekage was able to imitate this ability using iron powder instead of sand, and his special magnetic powers. He often moulded the iron powder into weapons and used them as his part of his main fighting style.

When used in sufficient quantities, this iron sand can be equipped in various ways, 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 user's magnetic field is in effect, even bypassing a Chakra Shield.

Shinki is able to control and change the shape of the iron sand through a electromagnetic field.

Trivia

 * When Sasori made the Kazekage into a puppet, he drenched the sand in poison, making it more lethal in battle.
