Abstract
A golf club head is provided with a cavity which has a pair of side walls which extend at an angle of about 0.degree. to about 50.degree. to the hosel of the club head. The shape of the cavity positions a substantial portion of the weight of the club head in the upper portion of the toe of the club head and in the lower portion of the heel of the club head. The orientation of the weight of the club head provides a substantial moment of inertia about an axis which extends through the center of gravity at an angle of about 45.degree..
