Sandaime Kazekage was said to be the most gifted Kage in Hidden Sand's history. He disappeared under mysterious circumstances right before war broke out. He had the ability to change his body's chakra into magnetic fields. Seeing a previous Shukaku host manipulate sand, Kazekage surmised he could do something similar with tiny pieces of iron. He used this ability to develop "Satetsu" or Iron Sand. He could control this sand in any fashion he wished through the magnetic field. This allowed him to form weapons whenever he needed. This jutsu came to be known as Suna's deadliest, and granted him the honor of being called the greatest Kazekage.
