Sword of the Thunder God

This sword was owned by Tobirama Senju. It was stolen from Konohagakure by Idate Morino because Aoi Rokushō told him that he could become a Chūnin if he managed to get the sword. Aoi then took the sword for himself until it was destroyed by the combined efforts of Team 7.

The sword glowed bright yellow and was apparently infused with pure electrical energy, hence its name. The blade was unusual in that, though it appeared to retract into or emanated from the hilt or crossguard like a Lightsaber (and producing the same sound), it was apparently solid and subject to stressing and being shattered when sufficient force was applied. The forces required were extraordinary, however, as a weakness in the blade had to be created first with a sustained attack from Sasuke's Chidori, an extremely powerful lightning based attack itself, and then in order to actually break the sword it needed to be struck with Rasengan in the exact weak point that was created. Before then the sword could easily cut through both Chidori and Rasengan without harm.

It is, however, extremely valuable from a combat point of view, as Aoi claimed that the wielder of the blade was essentially invincible. However, if one relies on the sword too much, it was proven that with skill and teamwork, a Jōnin wielding the sword can still be defeated by a pair of Genin, albeit they were using A-rank techniques. On the other hand, it is also possible that not being the proper owner of the blade and having had no formal training on its use, Aoi simply did not know how to use the weapon to its full potential.
