ABSTRACT:
Presented is a golf shaft designed to have a "kick" point or "flex" zone at a predetermined location along the length of the shaft. How and where the shaft bends or flexes during the down swing has a strong influence on how the club "feels" to the golfer. How and where the shaft bends during the down swing is determined by the construction of the golf shaft and presented herewith is a golf shaft structure and method of making it which controls the position of the flex point along the length of the shaft so that a variety of shafts having different flex characteristics may be manufactured to suit the dictates of individual players.
