    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. The invention additionally includes an iron-type golf club head, including a top rail surface portion projecting rearwardly from an upper periphery of the front striking face and extending between the toe and heel portions. The hosel is offset and inset, and extends generally upwardly and forwardly only from the heel end portion of the top rail, such that the hosel does not occupy any portion of the front striking face and does not impede contact between the front striking face and a golf ball.

    Abstract translation: 相关的铁型高尔夫球杆头组，其中组中的每个头部采用相同尺寸的减震板。 每个球杆头包括具有用于冲击高尔夫球的前冲击面的基本上平面的刀片元件和与前击球面相对的后表面。 周边加权元件与后表面的外周边的至少一部分一体地形成并且从后表面大致向后延伸。 后表面的未被周边加权元件覆盖的其余部分限定了基本上被周边加权元件的内周表面包围的开放空腔的底部。 限定开放腔的底部的后表面的其余部分的面积和形状在相关组的每个球杆头中基本相同，从而可以在每个球杆头中使用相同尺寸和形状的振动阻尼板。 本发明还包括铁型高尔夫球杆头，其包括从前冲击面的上周向后突出并在趾部和跟部之间延伸的顶部轨道表面部分。 插鞘是偏移和插入的，并且仅从顶部轨道的后端部分大致向上和向前延伸，使得插鞘不占据前打击面的任何部分，并且不阻碍前撞击面和前冲击面之间的接触 高尔夫球。
