The Dynacraft Driving Iron features a thin, special vacuum heat treated, high-strength forged 17-4 stainless steel face with variable thickness to push high COR to the maximum limits. The hollow-bodied construction positions weight low and rearward for advanced perimeter weighting and a more piercing driving trajectory than a comparable lofted fairway wood. It is designed primarily as a control club off of the tee but can be an option for approach shots from the fairway from preferred lies. Assembled with a steel-shaft (Uniflex) and rubber grip.
