Abstract
A golf club shaft used with putter type club heads for making a putting stroke on the green of a golf course is made from high-modulus fibers which results in an ultra-high stiffness putter shaft with high frequency, low tip deflection, and high torsional and bending rigidity. The ultra-high stiffness putter shaft prevents unwanted face twisting during the impact of a golf ball during a putting stroke, allowing for greater putt accuracy.
