Abstract: Structure and method of manufacture of a golf club such as a putter and comprising a metallic and cavitied die-cast head core, an impact vibratory plate member over the cavity and communicating resonating chambered elements including the cavity and the club shaft. The head core is shaped and dimensioned for balance and for bringing the center of gravity of the club forward. The plate-covered cavity is shaped and dimensioned to control ball deflection for production of accurate top spin of the ball and to minimize damping of sound frequencies therein for transmission to the shaft.
