Sword of Totsuka

The Sword of Totsuka, also known as the, is a variant of the Sword of Kusanagi. It is sheathed in a sake jar; the blade is actually the liquid inside the gourd that is released and shaped, rather than a conventional sword. It is an ethereal weapon, with an enchanted blade capable of sealing anything it pierces. Those who are stabbed by the sword are drawn into the jar and trapped in a genjutsu-like "world of drunken dreams" for all eternity; by extension, Itachi also managed to remove the Cursed Seal of Heaven from Sasuke by stabbing and removing Orochimaru from Sasuke's body. Orochimaru sought the sword for all his life and Zetsu commented that he could never find it.

Along with the Yata Mirror, the Sword of Totsuka is a weapon carried by Itachi's Susanoo and is held by a third hand growing from its right forearm. Together, they were said to have made Itachi essentially invincible.
