The Renbatō, or "Repeater", is one of the satsujinken swords forged by master swordsmith Arai Shakkū during the Bakumatsu.
Design[]
While stored, the Renbatō appears as a set of twin katana, but a section on each hilt comes off to reveal interlocking pegs, allowing the two blades to connect and form the sword's true form - a single sword with parallel blades. This weapon is designed so as to leave close-set parallel wounds when it cuts an opponent; since wounds of this nature are nearly impossible to stitch closed, infection is nearly unavoidable and anyone on the receiving end of one of Renbatō's blows will die a painful death by disease if not cut down in the duel. Rather than being an unbeatable sword, it is a sword that ensures death for its opponents. However, the Renbatō does not seem to be particularly durable.
History[]
Renbatō ends up in the hands of "Sword Hunter" Sawagejō Chō and sees its final battle against Himura Kenshin, who shatters its blades with ease.
