Abstract
The present invention is a golf club head whose engagement surface is formed between an upper metal piece and a lower metal piece, the upper piece being composed of relatively lighter and less dense material and the lower piece being composed of relatively denser and heavier material. The union of the two pieces is along a single unitary plane. By utilizing this type of design, in which two engagement surfaces of different metallic composition are joined on a single plane to create a continuous engagement surface on the club head, the benefits of improved balance and enhanced performance that result from the lower piece being heavier than the upper piece can be achieved without the need to fit a precisely engineered weight into a precut opening in the golf club head, thus making the manufacture of golf club heads easier and more efficient.
