Steel Release: Manipulated Blade Dissolution

After making the needed hand signal, the user charages chakra into their hand and blocks the strike of a bladed or metal weapon, such as a shuriken, kunai, or sword. The chakra not only absorbs much of the weapons impact, but it also inject itself into the attacking object. The chakra then disrupts the iron atoms within the blade of the weapon and severely weakens them chemically, similar to rusting. The blade then either turns black and breaks away in pieces, melts, or shatters on impact depending on the amount of chakra injected and the percentage of iron atoms within the metal. It is best to use this technique with some armor, as the attacking weapon can still deal damage. Also, precise timing is needed to block the attack, or the weapon can have full effect is the timing is off.
