Bottom portion of a golf club head

A golf club includes a shaft having at one end a hollow metal wood club head. The club head defines a face, a lower sole portion, an upper portion, and a side wall. The sole portion is generally thicker than the upper portion, and preferably approximately one and one-third to six times as thick. As a result of the thicker construction of the sole portion relative to the upper portion, the center of gravity of the club head is relatively low. The lower center of gravity permits a golfer to more easily swing the face of the club head under a golf ball. In a second embodiment, portions of the side wall are provided with a generally thicker construction relative to the upper portion of the club head. In a third embodiment, the sole portion is made from a material having greater mass per unit area than the upper portion.
