Sword of the Thunder God

The Sword of the Thunder God is a blade was once wielded by Tobirama Senju.

History
The Sword was previously stolen from Konohagakure by Idate Morino after Aoi Rokushō deceived him with a promotion to chūnin. Aoi then took the sword for himself but lacked the knowledge on how to use the sword at its full potential. The sword also came with a scroll of instructions on how to properly wield it that Idate had stolen back from Aoi. During a mission to sabotage the Todoroki Shrine race, Aoi wielded the Sword against Team 7, only for it to be destroyed by their combined efforts.

Appearance
The blade 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 emanate from the hilt or crossguard like a lightsaber (and producing the same sound).

Abilities
The sword itself had many uses that involved its ability to manipulate lightning. Being made of concentrated lightning, once making contact with the enemy, it would give them a strong electrical shock capable of incapacitating them afterwards. The sword was capable of producing electrical rings of energy that can suspend the enemy in mid-air while continuously shocking them. The wielder of the blade can use this to throw the enemy a good distance away. Defensively, the blade can channel its electrical properties in mid-air to block incoming attacks. As shown in Aoi's fight with Naruto and Sasuke, the blade was shown to not only be able to easily cut through any solid object, but also through chakra as well, including A-rank techniques like the Chidori and Rasengan.

Trivia

 * The hilt of the sword seems to resemble a vajra, mimicking the symbol of the blade's owner's clan.
 * Although an anime-only tool, this sword first appears in the video game Naruto: Path of the Ninja 2 by the name of Raijin Sword, with the description reading, "Second Hokage's blade". It is one of the secrets within the game and is unlocked by obtaining the Silver Blade Ticket and talking to Shizune afterwards.
