发明名称 Golf club
摘要 A set of golf club wedges each having a club face (10) is disclosed wherein the lofts of the individual clubs progressively increases. The hitting surface of each club head may take the form of an insert (12) that includes a series of grooves, the design of which is varied from club to club to provide increasing friction with loft. As a result, a golfer can impart the same amount of spin to a golf ball with each of the wedges despite a substantial difference in loft and club head swing speed between the respective clubs. In addition, the surface roughness of the hitting surface may also be increased as loft increases to further control the spin imparted to the ball.
