Forged iron is made from soft iron for a better flight and better style. The head now looks even sharper with a thinner top blade, a thin-walled face to enhance resilience and the vibration-absorbing material FLASH ONE*1 in the hollow space. These features provide a powerful play and softer hitting sensation. An easy-to-address straight neck and an effortless strike are all additional features of this forged iron, which also has reinforced laser milling to provide greater wedge stability. The original steel shaft comes in "Easy Long" and "Controllable Short."
The SOFT STEEL M-37 has the lightest steel shaft in PRGR history besides the new Speed Impact Shaft (carbon). It provides great direction and distance and an easy and steady swing. The shaft is more rigid around the grip and bends more smoothly from the center to the head than any other steel shaft.
