Abstract
A variable stiffness striking implement, such as, for example, a ball bat typically used in baseball, softball, or rubber ball. The striking implement, preferably has a separate barrel and handle. A wedge and joint attached directly to the handle or indirectly to the handle using an interface portion engage the interior surface of the barrel. Most preferably, the wedge and joint are molded about the interface portion and a handle preform is then inserted into the intention of the interface portion and the handle is then molded. Wedge hardness is selectable and a stiffness member may also be employed. Stiffness member hardness may be selectable or may be adjustable by varied adjustment of a cap in relation to the barrel. Alternatively, the cap may not be adjustable in relation to the barrel so that a selected stiffness member hardness is fixed.
