  • Set of iron-type golf club heads
    Patent number: 5800282
    Abstract: A correlated set of iron-type golf club heads, wherein each head in the set employs the same sized vibration damping plaque. Each club head includes a substantially planar blade element having a front striking face for impacting a golf ball, and a rear surface opposite the front striking face. A perimeter weighting element is formed integrally with at least a portion of the outer perimeter of the rear surface and extends substantially rearwardly from the rear surface. The remainder of the rear surface not covered by the perimeter weighting element defines the bottom of an open cavity which is substantially surrounded by an inner peripheral surface of the perimeter weighting element. The area and shape of the remainder of the rear surface that defines the bottom of the open cavity are substantially identical in each club head of the correlated set, thus making it possible to use the same sized and shaped vibration damping plaque in each club head.
