Do steel shafts need to be PUREd?
Absolutely. Steel shafts are made by heating a flat piece of steel and wrapping it around a template called a mandrel. The ends of the steel are welded together to form what is called a weld seam. The location of this weld seam greatly affects the way the shaft performs. Straightness and roundness are also an issue in mass-produced steel golf shafts, and the SST PURE process takes all of these factors into account when PUREing a steel shaft.
