- Users: Kakashi Hatake, other Ninja
- Description: A chain with weights in both ends, that can be swung at opponents or even used as an anchor. Kakashi Hatake used it as a counter against Pain's Deva Path's Banshō Ten'in technique and later used a chain in attempt to restrain the Deva Path's arms and leave him open to the Akimichi clan's double team attack.
- Traditional use: Manriki-gusari or Kusarifundo was designed to strike, ensnare or trap an opponent. One tactic was to bunch the chain in a fist and fling one weighted end into the face, groin or solar plexus of an opponent, quickly and discreetly disabling or even killing them. Typical manriki-gusaris are approximately three feet long. The manriki-gusari could also be thrown before drawing another weapon, thus possibly confusing, or surprising the enemy. Many forms taught to hit directly with only one swing, so the opponent would not expect the blow..
