Sword of Totsuka

The Sword of Totsuka is a variant of the Sword of Kusanagi carried by Orochimaru. Along with the Yata Mirror, the Sword of Totsuka is a weapon carried by Susanoo that exists only in the user, being made up of chakra. Contained in a gourd held by Susanoo's third fore arm, the blade is actually the liquid inside the gourd that is released and shaped, rather than a conventional sword. Since the sword is made up of chakra like Susanoo itself, it exists only within a Mangekyō Sharingan user and can never be found.

Itachi has been seen using it to slash several targets at high speed, when he severed seven of the heads of the Eight Branches Technique with several swings. Also functioning as a sealing device, the weapon was used to place Orochimaru in an eternal genjutsu, after which he was sealed in the gourd.
