Abstract
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.
Claims16
A set of golf clubs having heads of progressively increasing loft, each of the heads comprising
- (a) a body having top, bottom, toe and heel portions and a striking face area containing a recess;
- (b) an insert secured within said recess, an outer surface of said insert being substantially flush with a non-recessed portion of said striking face area;
- and
- (c) at least one of the thickness and density of said inserts increasing within the set of golf clubs as the loft of a club increases, whereby the mechanical properties of individual clubs within a set of clubs can be altered to enhance the performance of the clubs.
