Sword of Kusanagi (Orochimaru)

The Kusanagi Sword is the Kusanagi of Japanese legend. Orochimaru retrieves his Kusanagi by opening his mouth and extending a snake which then opens its mouth and produces the sword. Orochimaru was seen producing the sword handle first so he could use it freely, or blade first to attack his opponent instantly.

The sword can extend its blade to attack from long distances, levitate in the air according to Orochimaru's command, and it can cut through almost anything. Even Enma, who is able to turn himself into a diamond-hard staff, stated that the Kusanagi blade could damage him greatly. It should be noted that Orochimaru's Kusanagi could not pierce Naruto in his Four-Tailed form. The sword has been seen transforming into a small snake and returning to Orochimaru.

When Orochimaru reemerged from Sasuke Uchiha through his Eight Branches Technique, he was sealed by Itachi Uchiha's Sword of Totsuka, taking the Kusanagi that Orochimaru was holding with him.

The Kusanagi appears differently from the manga to the anime. In the manga, the Kusanagi looks more like a standard katana, while in the anime it is a double-edged jian.

Trivia

 * Sasuke Uchiha refers to the chokutō he carries as a "Sword of Kusanagi", but it carries none of the unique attributes that Orochimaru's does.
 * The Totsuka Sword wielded by Itachi Uchiha's Susanoo is also said to be a "Sword of Kusanagi", although this has been popularly mistranslated as it being the perfect counter to the Sword of Kusanagi.
