Manriki-gusari

The manriki-gusari is a chain weapon originating in Japan. It is weighted on both ends, and is useful in heavy strikes, limb/joint locks, and trapping weapons.

Michelangelo uses one in a Season One episode of the 1987 series, calling himself "master of the manriki-gusari".

The manriki-gusari is also the primary weapon of Nightwatcher, which he wields in pairs.
