  • Patent number: 6371866
    Abstract: A compact golf club set is provided having a complete set of thirteen golf club heads, two club shafts, and two club handles, all attractively positioned and retained, in a unique briefcase-style carrying case, which provides ready access to golf shoes, towels, balls and tees. The various club shafts and club handles combine to form a long and a short club assembly, corresponding with a typical wood and a typical putter, respectively. The club shafts couple directly to the club heads without an intervening shank, which allows a complete thirteen club head set to be compactly and efficiently positioned in receptacles in the carrying case.
