Sword of Kusanagi

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