Susanoo Weapon

A simple chakra blade that the user's Susanoo is capable of creating and wielding during the technique's incomplete stage of development, and just like the Susanoo itself, each particular blade is unique to the individual involved. Sasuke Uchiha's resembles a regular blade and is wielded by the left arm of his Susanoo. However, Madara Uchiha possesses two distinct swords that are instead wielded by the right arm of each side of his Susanoo and feature undulating blades, which resemble kris.

Despite their diverse appearances, each sword is extremely effective, due in part to the considerable strength of the Susanoo that wield them. Sasuke was able to use his to cut through several stone pillars in a single swing, whilst Madara's could break through the combined defence of Gaara's Shield of Sand and Ōnoki's Rock Golem, which together were capable of resisting even his Yasaka Magatama attack.

After acquiring his Eternal Mangekyō Sharingan, Sasuke's sword is coated with the black flames of Amaterasu, which ignites anything it pierces.
