An idea comes...

I think i may have found the perfect weapon system...

Something similar to a well-known particular character from a certain marital arts movie, modified and worn on the wrist, possibly on a forearm gauntlet, this non-lethal weapon would hurl a spinning bola or weight on a powered rope or mono-filament line out to a target and then retract it back.

I have a design in mind, but....but,...a launcher small enough to fit on the wrist,
