Bruce Lee, David Carradine and Carl Douglas, in the 70's everybody was "Kung Fu fighting"
Therefor the Home made Nunchuk was born
A chain stolen from a lavvie cystern.
Your Ma's broom/rake/hoe handle sawn into lenghts
A couple of nails and Boab's yer uncle."You will have someones eye out with that".
Advantages - Cheap and available.
Drawbacks - Flimsy chain liable to snap, Handles flew of regularly as the nails were traditionally hammered in with a half niddrie, Splinters in the newly created blisters on your hands. Hitting yourself in the eye, back of head, knee and baws. Getting a thick ear when your ma went to rake the back green a week later.
Ah but they looked the part
