Iron Sand Control is an ability built on the Magnetism element. The user turns their chakra into a strong magnetic field and uses it to control iron dust. This powder is collected in advance and carried along. Blades, spikes, walls, waves and other constructions are formed from the iron sand. Dense masses of sand are capable of binding movements, crushing obstacles and clogging the joints of puppets, rendering them useless. The magnetic field also provides passive protection: metal weapons thrown at the user are deflected. The technique requires large volumes of sand and high precision of control, therefore it reveals its full power only in an experienced shinobi. Iron sand control is considered the strongest ability among similar ones - ordinary sand and gold sand - due to its greater durability and deadliness.
