Ever Make Nunchuks as a Kid?
I made many a pair. Broomsticks, nylon cord, screw eyelets, and electrical tape became a deadly weapon after an hour in the basement with Dad's tools. I made a smaller pair that I would tuck into my waistband at the small of my back and cover it with my shirt. I would walk around my neighborhood begging for some ninja to come on out and try to fuck with me. I was never attacked by evil ninja though, they must have known I was packing.
