Susanoo Weapon

This is a simple chakra blade that the users of Susanoo are capable of creating and wielding and just like the Susanoo itself, each particular blade is unique to the individual involved. However, as Susanoo evolves, so does the sword.

Forms

 * Sasuke Uchiha's resembles a regular katana that is somewhat curved at the end and is wielded by the primary left arm of his Susanoo. Sasuke was able to use his to cut through several stone pillars with ease.
 * Sasuke's sword, in his Eternal Mangekyo Sharingan form, was composed of Amaterasu, becoming a blade capable of burning anything.
 * Madara Uchiha's version possesses two distinct, undulating blades, which resemble a kris that are instead wielded by the right arm of each side of his Susanoo when it is in its complete, armour-less and final, unstabilised form.
 * When Madara manifests his Susanoo in its final, stabilised form, the blades become straight and more resemble traditional katana, complete with sheaths. These are held in the Susanoo's secondary arms and wielded with the primary ones. Madara could use these to cut through mountains with a single swing.
 * Itachi Uchiha's Susanoo sword is curved in nature and resembles a dagger or tantō rather than a sword. He manifested this while only using his Susanoo's ribcage and arms, during his battle against Kabuto Yakushi. He was able to use this blade to cut through Kimimaro's bones, which were stated to be harder than tempered steel.

Trivia

 * After acquiring his Eternal Mangekyō Sharingan, Sasuke's Susanoo was seemingly able to wield a blade composed from the black flames of Amaterasu, which ignited anything that it pierced. However, it is unknown as to whether this blade is a sword or simply an arrow for his bow.
