Sasori's favourite human puppet was the Third Kazekage, which retained its Magnet Release, which in turn grants Sasori access to the Iron Sand techniques. When mixed with Sasori's poison, the Iron Sand was given a more lethal edge. The Iron Sand could also be used to fill up the joints of other puppets, thus immobilising them. Due to the Iron Sand being derived from the Third's ability to convert chakra to magnetism, this grants Sasori immunity from metallic weapons. The Third's puppet's right arm held several poisoned blades, while the left arm could open up to reveal several summoning seals that summoned thousands of similar arms to attack the target. These arms were capable of crushing an opponent, emitting poisonous gas clouds, and releasing wires that dragged the opponent into the gas cloud. If these arms were cut off, a small buzz-saw took their place.
