Abstract

A novel golf club construction is provided herein. It includes a club head and a shaft. The club head has a tapering neck. The shaft has a lower end extending into the club head and passing through the neck. The golf club construction further has a cured resin impregnated fibrous material wrapping around the shaft and an adjacent portion of the shaft in a fashion that provides a gradually decreasing cross-section from the neck to the shaft. The cured resin impregnated fibrous material wrapping integrally interconnects the club head and the shaft by cohesive bonding upon being heated and pressurized. There is thus no visible seam at the joint between the club head and the shaft.
