Golf club shaft

A tubular steel golf shaft comprising a grip section, a tapered mid-section and a tip section. A loading zone is selectively formed along a portion of the shaft, preferably in the tapered mid-section, comprising a continuous series of closely spaced micro-steps, or reductions in diameter, each of which are less than 0.5 inches in length. Each micro-step section, in the direction from the grip section toward the tip section comprises a first peak which descends to valley and then ascends to a second peak. The diameter of the first peak is greater than the diameter of the second peak. A method of manufacturing the golf shaft is also disclosed.
