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. Despite their variations, each sword is extremely effective, and as Susanoo evolves, so does the sword.

Forms

 * Sasuke Uchiha's Susanoo is capable of utilising a blade resembling a sabre, wielded by its primary left arm. Sasuke was able to use it to cut through several stone pillars with ease.
 * Upon reaching its final form, the composition of the chakra orb held by the secondary right arm of Sasuke's Susanoo changed to that of Amaterasu's black flames, from which Sasuke is able to forge into the shape of a blade that his Susanoo's primary right arm wields.
 * Madara Uchiha's Susanoo possessed two distinct, undulating blades, which resembled a kris. The blades were wielded by the right arm of both sides of his Susanoo in both its incomplete and complete forms, and could even be manifested alongside one of the arms of his Susanoo whilst only surrounded by its aura. In its final, unstabilised, form, the size of the blades increased dramatically and they were wielded by its primary right arm and primary left arm.
 * When Madara manifested his Susanoo in its final, stabilised form, the blades became straight and more closely resembled traditional katana, complete with sheaths. Said sheaths were held with his Susanoo's secondary arms, while the swords were wielded with its primary ones. Madara could use these to cut through a range of mountains in the distance with a single swing. The blades could also be partitioned to a Tailed Beast Ball during its formation, increasing its offensive power to such a degree that it could even obliterate five Rashomon gates, proceeding with only a slightly altered trajectory to the opposite shore of a massive body of water.
 * Itachi Uchiha's Susanoo wielded a blade which was curved in nature and resembled a dagger or tantō rather than a sword. Itachi demonstrated the ability to manifest this blade while only forming his Susanoo's ribcage and arms, during his battle against Kabuto Yakushi. With it, he was able to cut through Kimimaro's bones, which were stated to be harder than tempered steel.

Trivia

 * In Naruto Shippūden: Ultimate Ninja Storm 3, Madara's Susanoo Swords are capable of spinning, giving them a drill-like ability.
