I gotta go with nunchuks. Anything you sling around on a chain seems silly to me. It seems like nunchuks are only good weapons against the unarmed. Anyone else has more range, usually something sharp in play and there isn’t a limp chain in the middle reducing the force of your strikes.
there is a nice scene in one of the John Wick movies where Wick shows off some practical nunchuk work. The nunchuks themselves had of course come from a display case.
