ABSTRACT:
A system of interchangeable club heads sharing one or more shafts and golf bag for carrying the club heads and one or more shafts. The club heads contain a shaft segment to set club length and a coupler to interconnect to the shaft and grip. The shaft contains an opposite gender coupler. The system is very lightweight and much more portable than a conventional set of golf clubs. It also creates the opportunity for players to match club heads with shafts with differing performance characteristics. Additionally, it solves a problem for golfers using long shafts on putters. These long shafts can now be disassembled for storage and transport.
