Sword of Kusanagi (Sasuke Uchiha)

Sasuke Uchiha claimed that the chokutō he wields is a Sword of Kusanagi; it has a black scabbard and matching handle, and is a larger size than a normal chokutō. Despite this, it has none of the specialties 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.

Danzō Shimura took the sword from a paralysed Sasuke and attempted to kill him with it, but was forced to drop it when Sasuke unleashed Susanoo. The sword was not seen being recovered after the battle, though Sasuke was seen in possession of it after transplanting Itachi's eyes.
