Sword of Kusanagi (Sasuke Uchiha)

Sasuke Uchiha claimed that the chokutō he wields is a Sword of Kusanagi. Despite this, it has none of the special as the one Orochimaru wields, such as extension of the blade and the ability to cut through almost anything, both of which are natural attributes of the Kusanagi.

To compensate for this, Sasuke can channel his lightning chakra into the blade with chakra flow, which will increase its sharpness greatly through high frequency vibrations, as well as increasing its cutting range. This would allow Sasuke to cut through almost anything, as well as numb the target who has been pierced by this lightning blade.

During Sasuke's fight with Danzō Shimura, who tried to take the sword to kill a paralyzed Sasuke with it, when Sasuke unleashed Susanoo, the elder was forced to drop it. The sword has not been picked up, and was presumably left behind at the Blue Samurai Bridge.
