Sword of the Thunder God

This sword is owned by Rokusho Hōzuki. The blade glows bright yellow and is infused with pure electrical energy, hence its name. The blade appears to retract into or emanates from the hilt or crossguard like a lightsaber (and producing the same sound).

It is, however, extremely valuable from a combat point of view. The sword itself had many uses that involvs its ability to manipulate lightning. Being made of concentrated lightning, once making contact with the enemy, it gives them a strong electrical shock capable of incapacitating them afterward. The sword is capable of producing electrical rings of energy that can suspend the enemy in mid-air while continuously shocking them. Rokusho 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. The blade is not only be able to easily cut through any solid object, but also through chakra-based substances as well.
