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 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 paralyzed 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.

Usually when Sasuke battles a powerful enemy he lets go of his sword at one point of the fight and even though he's rarely seen recovering it he always posseses it afterwards
