The head portion is positioned to be gripped by one hand and the lower handle grip portion positioned to accommodate the other hand of a batter on respective sides of the articulating joint. The articulating joint is a spring means secured on one side to the head portion and on the other side to the handle portion so that at rest the handle portion is an axial extension of the head portion. A bumper is provided between the head portion and the handle portion in prevention of "pinching".
