History:After Sasuke joined Orochimaru and after much training he became a sword master, mainly of the Chokutō. 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 natural specialties as the one Orochimaru wields, such as the 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.
