Description The Forged Evolution II Irons are designed for the low-to-mid handicap player. These irons are manufactured in one-piece and are 100% double forged in Japan. Each head has its own unique design that is 10% different from the previous loft, thus creating a seamless set. The longer irons are very forgiving due to the increased perimeter weighting and the shorter irons are easy to control due to the muscle back design.
