Those who are stabbed by the sword are drawn into the jar and trapped in the genjutsu like world of drunken dreams for all eternity, by extension, Itachi Uchiha also managed to remove the Cursed Seal of Heaven from Sasuke Uchiha by stabbing and removing Orochimaru from Sasuke Uchiha’s body. It can also cut through objects like a normal blade, thereby giving the wielder great versatility in his attacks. Although the speed of the sword is evadable, it was able to catch Orochimaru off guard and Uzumaki Nagato who was being controlled by Kabuto. Being a variant of the Sword of Kusanagi, this sword can cut through almost anything, as seen when Itachi Uchiha easily decapitated seven of Orochimaru eight headed snakes. 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 wielded by Itachi Uchiha’s Susanoo, with the gourd being held by a third hand growing from its right forearm, while the actual blade is wielded by it’s right hand. Together, they were said to potentially have made Itachi Uchiha completely invincible.
