Abstract
The invention relates to a set of golf clubs employing a two-piece golf club shaft wherein the lengths of the first and second shaft members vary as the loft of the golf club varies. The set of clubs includes a plurality of golf clubs having varying lofts extending from lower loft golf clubs to higher loft golf clubs, wherein each golf club includes a club head and a shaft having a distal end and a butt. Each shaft includes a first member having a first end located at the butt end of the golf club shaft and a second end positioned slightly short of the distal end of the golf club shaft. A second member is secured to the second end of the first member. The second member extends from the second end of the first member to the distal end of the golf club shaft and includes a first end securely coupled to the second end of the first member and a second end which is ultimately secured to a golf club head. The second member progressively decreases in length as the plurality of golf clubs extend from the lower lofted golf clubs to the higher lofted golf clubs.
