Abstract: A golf club head having improved weight distribution comprising an integral hollow metal body with a bottom wall including a cavity recessed inwardly of the body throughout an extended area which lies rearwardly of the front striking face and inwardly of the heel and toe such that the ground engaging sole area of the head comprises a front rail portion adjacent the front striking face and side rail portions joined to the front rail portion and extending toward the rear wall. The side rail portions disposed between the center of percussion and the heel and toe areas. The recessed cavity has a size and depth sufficient to result in a concentration of club head weight in the area surrounding the center of percussion and to produce an elevation in the center of gravity of the head relative to the ground engaging sole area.
