Abstract: A subject-matter of the invention is a flexible nunchaku having two striking bodies (3, 3′) connected to an expander (2) which each have an inner body (4, 4′) and in their longitudinal direction one jacket (5, 5′) each made of plastic foam or foamed rubber, with the the inner body (4, 4′) being formed in each case by a highly flexible hose (4, 4′) without any filling of its inside which is inserted into the jacket (5, 5′) and firmly attached. This nunchaku has the advantage of good flexibility with sufficient stability so that choking and blows with physical injury or damage are excluded therewith.
