Once i made (with help) a pair of nunchakus, of metal.

The pipe was just a metal pipe, a bit rusted, and the chain was a normal chain of 7 links.
The chain was solder to the pipe, like this:


And in the end of the pipe i add a cork from a wine bottle, so it doesnt have cutting edges, like this:

The black paint is an special painting for rusty, that stop the rusting, and also eliminates what it have (you can find it in any hardwork store)
I think that the best idea you can use is the cork end, very usefull!
The overall weight of each is 680grs, a bit heavy, but excelent for training!
Hope you like it!
