发明名称 Golf club set with variable thickness and/or density face inserts
摘要 A set of golf clubs is characterized by club heads having striking face inserts at least one of which varies in thickness, density, and/or material from the other inserts so that the heads have different centers of gravity. Preferably the long irons in the set have a lower center of gravity (because of thinner or less dense inserts) to increase the trajectory of a struck golf ball. The short irons have a higher center of gravity to reduce the trajectory of a struck golf ball.
