The method includes using a specifically designed and separate mandrel for each club shaft of the matched set. Further, the method includes sequentially wrapping a specifically designed and separate group of patterns around each mandrel for each club shaft of the matched set. This procedure allows the manufacturer to specifically design each club shaft of the set of golf clubs. The resulting individually matched set of golf clubs has more consistent feel, flexure, frequency, weighting and torque characteristics. Additionally, the club shafts provided herein have improved swing weight characteristics for lighter heads.Field of SearchShaftReduced air resistance Including nonmetallic material or vibratory wave modifying feature Filament (e.g., fiber, etc.) or sheet wrapped about shaft longitudinal axis Including metal And metal Sections connected along longitudinally extending seam Shaft tapered in steps Method Club set Interchangeable handle, striking face, or shaft Particular correlated shaft flexural characteristic Particular correlated head characteristic Mass distribution | |
