  • Patent number: 6074309
    Abstract: Golf club heads, both woods and irons, have recessed areas in the striking faces of the club heads with an insert secured therein. The insert is of a laminated structure having multiple layers and so constructed that the outer layers are of a substantially high strength to weight material and the center layers are of a relatively lower weight material. This structure allows the insert to be reduced in weight so as to allow the weight difference to be repositioned about the perimeter of the club head to achieve optimum weight distribution. One of the outer layers is preferably perforated to permit visual inspection of the center layer.
