Rope

Wire Strings can be used for rappelling, manipulating weapons, or to bind and restrict the movements of an opponent.

They are used in the Manipulating Windmill Triple Blades, and the Manipulated Shuriken Technique to manipulate attacking objects. They are also used in the Dragon Fire Technique as a method of guiding the attack to strike the opponent. The sword Nuibari has a very lengthy wire attached to it to bind its opponents together.

Ace Korimachi uses wire strings made of Metrochronium, a synthetic metal of his own design, effectively making them indestructible and heat resistant. They are so thin, that when handled and used, they look as if they are invisible. Due to their natural cutting edge, they can cut through most objects, compounds and substances with ease.
