Name: Triple-Bladed Scythe (三刃の大鎌, Sanjin no Ōgama)
Debut (Manga): Chapter 312
Debut (Anime):Shippūden Episode 71
The Triple-Bladed Scythe is the primary weapon of Akatsuki-member Hidan. It's main purpose is to aid him in collecting blood for his Curse Technique: Death Controlling Possessed Blood ritual. Because of this, it is designed, not so much to kill the target, but to wound them, no matter how big or small the wound.
The three blades get smaller from top to bottom, giving the scythe a larger range, despite decreasing it's lethality. The scythe is attached to a long cable, wound around two spools on Hidan's left hip. This cable is strong enough to block kunai and allows Hidan to further increase the scythe's range by swinging it through the air. Despite its large size, Hidan is remarkably nimble in manipulating it, being even capable of using the scythe to deflect incoming shuriken. The scythe can also split up and it has various other functions and gimmicks that were never shown.
