Jūjiken

The Jūjiken (十字剣; Literally meaning Cross Blade) is the personal weapon of choice wielded by Shisaku.

Overview
A weapon of unknown origin found by Shisaku during his travels. The Jūjiken is a spear shaped weapon with two protrusions near the top of the blade, giving it the form of a cross, hence its name Cross Blade. The blade has impressive cutting power, able to slash through reinforced steel with ease. It also seems to be made of a mysterious substance that makes it unaffected by the effects of magnetism, giving its wielder an edge against over other blade wielders. When not in use, Shisaku transforms the blade into a small, cross pendant he wears around his neck.

This weapons most feared trait however, is its effect of disrupting chakra. When the wielders chakra is flowed through the weapon, it emits radiation spanning a radius of 15 feet. When the radiation hits something that's not doesn't match the wielders own chakra, it disrupts the control of the affected target's chakra flow, making them unable to wield it at all, so long as they're within' the radius of the radiation, making it also effective against Sage's and. This effectively makes the wielder immune to ninjutsu as well as and. This however, isn't as problematic if the opponent is well versed in or.
