This papercraft is the Zabuza's Blade, named Kubikiri Houcho, based on the manga / anime series Naruto. The paper craft was created by João Vieira. Zabuza's huge and powerful sword, Kubikiri Houcho. Though it is very powerful and can cut through anything, it is very heavy and is not a good weapon to use when fighting a very fast ninja.
Sasuke frees Suigetsu from his hydro capsule and requests his services. Suigetsu responds that he would gladly give them, on condition that he helps him find Zabuza's sword. They fail to find the blade at his grave, but learn that it is in the possession of a man named Tenzen Daikoku. Sasuke uses Tenzen's guarded fortress to test Suigetsu's combat abilities, and Suigetsu gets the blade without much effort. As promised, Suigetsu joins up with Sasuke, and goes with him to the Southern Hideout.
