| 摘要 | An improved golf club shaft and golf club, the shaft being of stepped configuration, having a uniform outer diameter butt end portion having a uniform wall thickness at least 10 inches (254mm) long, the uniform wall thickness being not greater than 0.012 (0.305mm) and a plurality of cylindrical step portions of progressively smaller outer diameter terminating in a tapered tip end portion having a wall thickness at the tip end of at least 0.024 (0.610)mm). The shaft is characterized by a redistribution of metal which results in a balance point closer toward the tip of the shaft, making it possible to use a lighter head without affecting the swing weight. | ||||||
