Driver technology has trickled down to irons for several years now. Problem is, irons are smaller than drivers, making it a more intricate task. For this iron, that meant creating a flexible face with a thin lip that wraps around the sole and topline, creating flex at impact to foster ball speed for on-center hits and minimize lost speed on off-center strikes. Flexibility, however, requires support. That comes from a cage-like structure with support beams.
