| This article is about the chokutō wielded by Sasuke Uchiha. For the sword wielded by Orochimaru, see Sword of Kusanagi. |
Sasuke Uchiha claimed that the chokutō he wields is a Sword of Kusanagi. It has a black scabbard and matching hilt (these are both blue in the anime), and is a larger size than a normal chokutō. Despite this, it has none of the natural specialities 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, but it's been repeatedly shown to be very durable.
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 the Fourth Shinobi World War, a reincarnated Itachi Uchiha, while cooperating with his brother, temporarily wielded the blade to engage Kabuto Yakushi. Sasuke was eventually fatally stabbed in the heart with this blade by Madara Uchiha.
