Abstract
A hollow golf club head with a concave portion is disclosed and claimed. The club head includes a metallic portion and a light-weight portion, which may be formed of plastic, composite, or the like. The concave portion allows the club designer to make a club head having very thin portions while still maintaining the requisite structural integrity. Convex bulges may optionally be provided to house weight inserts to enhance the playing characteristics of the golf club. The metallic portion of the club head may take on the appearance of a frame, into which several light-weight inserts are positioned. These light-weight inserts may be positioned in the crown, skirt, and sole of the club head. The club head is thus contoured such that its surface area is substantially large. The club head may also be formed of a single, relatively light-weight material.
