Sword of Nunoboko

The Sword of Nunoboko is a large, double-helix shaped sword, formed from the Ten-Tails Malleable Chakra and originally wielded by Hagoromo Ōtsutsuki.

According to Obito Uchiha, the sword is a holy weapon and the power of the sword is of such great magnitude, that while Hagoromo reportedly used it to create the world, Obito can use the sword to destroy it. Despite this, the sword itself is partially destroyed by Sasuke Uchiha's Susanoo Sword while enhanced by senjutsu and Nine-Tails chakra.
