It’s a Jean Claude van Damme movie. I think I misspelled his name but you know who I’m talking about.
Yeah...the twerp from Antwerp....LOL
I think they were called ‘hammers’ or just ball and chain.
A mace is a club with spikes and whatnot on the end.
A baseball bat with nails in the end is kinda like the modern equivalent and a motorcycle drive chain works as a ‘hammer’ pretty good.
