funchaku. foam nunchaku that are well balanced and heavy enough to freestyle with, but are legal in most places. if at some point i invested in a foam casting machine, and other things i would need for a small factory, do you think i could sell them? funchaku would also make traditional wooden nunchaku and possibly steel nunchaku. is there enough of a market that is not already gobbled up to pay back the cost? i would like your guys opinions.
