ABSTRACT:
A set of golf clubs, including both woods an irons, is disclosed in which the various clubs are constructed in their various parameters to aid the user to insure that each and every swing of the club follows the correct path and also to resist rotation of the club head and shaft during impact with the ball about a variety of pivot points on the shaft to assure that the ball will travel in a true flight pattern. The club head is weighted to locate its center of percussion near the toe of the head to reduce rotation of the head at impact about the shaft axis and the handle of the club is weighted to locate the center of percussion of the club below the club head to reduce rotation of the club about the pivot point defined by the base of the index finger of the lower hand in the grip. In addition the shafts of the clubs are stiffened above the club head so that the zone of maximum flexibility of the shaft is about 40 cm above the hosel of the club head whereby the head will be moved forwardly relative to the rest of the club at impact to impart greater force to the ball and distance to the hit. And, the club grip is enlarged to enable the player to apply a greater force to the club resisting rotation of the club shaft in the player's grip.
