ABSTRACT:
A cavity backed iron-type clubhead has a striking plate which has a point of least rigidity which is generally aligned with the center of gravity of the clubhead. The striking plate is formed between the front face of the clubhead and the back wall of the cavity. The point of least rigidity of the striking plate is adjusted by a rigidifying member on the back wall of the cavity which increases the thickness of the striking plate. The back wall may also include a rearwardly extending projection which is generally aligned with the center of gravity of the clubhead.
