These are one of the five tools created and used by the Inagara Clan. Made from a special chakra absorbing material, they augment the wielder's lightning nature chakra. The extra prongs on the back help the flow of the lightning. Attacks using these tools mostly revolve around either throwing them near an opponent to have lightning arc between them, or throwing them into the ground to create a region of electricity. Like their earth release counterparts, they can be seen around the Inagara grounds as a measure of defense.
