Susanoo Weapon

Overview
As user's gain more control over their respective Susanoo, they are able to extend their power by forming weapons. While particularly swords and bows; like the Susanoo itself, each particular blade is unique to the individual involved. Additionally, as the wielder becomes more powerful, their weapons do so as well.

Sword
This is a simple chakra blade that the users of Susanoo are capable of creating and wielding. . 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 kris. The blades were held by the right arm of both sides of his Susanoo in its incomplete and complete forms, and Madara could also materialise one while only surrounded by his Susanoo's aura. In the anime, Madara could manifest swords in all four of Susanoo's arms; the blades left traces of blue fire in the ground after impacting and could unleash tremendous shock waves capable of obliterating hundreds of shinobi in a single strike. When Madara's Susanoo entered its final form, the size of the blades increased dramatically and were wielded by its primary right arm and primary left arm.
 * When Madara stabilised his Susanoo's final form, the blades 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, giving it cutting power. Madara did so to prevent Hashirama Senju from grabbing Tailed Beast Balls with his Wood Release: Wood Human Technique.
 * 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.

Bow
Presently unique to Sasuke's completed Susanoo, it is capable of wielding an unusually shaped bow on its left arm. Not only can it be utilised to fire arrows created from the orb of chakra held in its opposing secondary arm, but it can also double as a shield strong enough to withstand attacks capable of shaving away at the terrain in its immediate vicinity.

The arrows, which are seemingly made with variable thickness based on the user's discretion, travel at a very high velocity and possess considerable piercing power; enough to easily breach a tree created by Wood Release. Even Kakashi, a ninja noted for his exemplary speed supplemented by the Sharingan's keen perception, was unable to dodge the arrows and forced to use Kamui to warp them away. Only Kabuto, while utilising the extrasensory capabilities of his Sage Mode, has been able to successfully avoid one of these arrows thus far.

Trivia

 * In Naruto Shippūden: Ultimate Ninja Storm 3, Madara's Susanoo Swords are capable of spinning, giving them a drill-like ability.
 * Upon reaching its final stage, the bow of Sasuke's Susanoo gained a notable increase in size, more closely resembling a shield. Additionally, the composition of the orb responsible for producing its arrows changed to that of Amaterasu's black flames. While initially utilised to manifest an armament of swords and smaller projectiles shaped from these flames, Sasuke later demonstrated the ability to create arrows from them as well.
