Abstract
Abstract A baseball bat made of a rigid material and having an elongated body with a free end tapering to a handle of a reduced diameter includes a cavity within the handle adapted to secure and receive a tubular member therein, a detachable knob with a chamber therein is secured within the cavity of the handle and to a tubular member inserted into the handle cavity. The tubular member includes a plurality of particles interiorly disposed therein, and a fluid interiorly situated within the tubular member. The tubular member is preferably secured to the detachable knob by one or more grooves, ridges, threads, or barbs on a inner surface of the detachable knob which mate with a corresponding set of grooves, ridges, threads or barbs, on a outer surface of the tubular member. The detachable knob is preferably secured to the handle by one or more grooves, ridges, threads, or barbs on the detachable knob mating with a corresponding set of grooves, ridges, threads, or barbs on a inner surface of the handle. A transfer cylinder may be attached to the tubular member by an elongated rod allowing for even greater shock dampening effects.
