ABSTRACT:
A nunchaku having two spaced apart rod-like elements or handle members, each element being formed of a plastic insert molded in a body portion which forms the balance of the element. The plastic insert, which is formed on nylon 6/6, has two spaced apart generally parallel apertures extending from one exterior sidewall of the element to the other exterior sidewall, the insert being disposed in one end of the element. The balance of the element is formed of high density polypropylene which is molded about the insert, the body portion having better impact resistance than the insert, and the insert, which receives a cord to secure one element of the nunchaku to another element of the nunchaku, having better wear resistance and greater strength than the high density polypropylene. Each element of the nunchaku is made by holding the plastic insert between intersecting surfaces in the mold cavities of each of two mold halves when the mold halves are brought together into their closed operative position, and by injection molding high density polypropylene, which has a lower melt temperature than the insert, about end surfaces and selected sidewalls of the insert.
