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 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.

Utilised Techniques

 * Iron Sand Drizzle
 * Iron Sand Gathering Assault
 * Iron Sand World Method
 * Magnet Release: Lightning God Self

Trivia

 * When Sasori made the Kazekage into a puppet, he drenched the sand in poison, making it more lethal in battle.
 * Magnetite, the main component of Iron Sand, is about 2 times denser than silica, which is the main component of sand, while gold is about 3.7 times denser than magnetite.
