Abstract: A composite golf club shaft is constructed having a reduced butt diameter of 0.400 to 0.560 inches in diameter. The shaft tapers without intentional discontinuities from the reduced-diameter butt section to a cylindrical tip portion having a standard tip diameter adapted to be attached to the hosel of a club head. By reducing the diameter of the butt portion of the shaft while maintaining the shaft free of substantial discontinuities, lead-lag flexure is increased uniformly, thereby improving the controllability of the shaft, and without inducing the artificial bending modes found in bubble shafts and other shaft configurations having intentional discontinuities.

Abstract: The set of irons have a cavity back surrounded by a perimeter where the perimeter is formed such that the geometric center or other intended impact position on the club face and the center of gravity of the club head coincide.

Abstract: A correlated set of golf clubs of the iron type is disclosed in which each club head has a cavity formed in the back surface thereof with specially configured weight pads formed integrally within the back cavity. The weight pads are so configured and positioned within the confines of the back cavity as to create desired heel-toe balancing of each club head wherein each club head's center of gravity physically centered, both horizontally and vertically of the club head, behind the visually-perceived optimal striking point. i.e., the apparent visual center of percussion, of the golf club's striking face relative to the golf ball at address. In the preferred embodiment the configured weight pads are so varied in size and position throughout the set of correlated golf clubs heads as to consistently maintain, for each head, the club head's center of gravity directly behind and in alignment with the club's apparent visual center of percussion.
