The Sub 70 639-MB Forged Black Iron is a study in beauty and efficiency of design The club head itself begins as a solid billet of DT-4 soft stainless steel. Each head is precision forged for unparalleled feel and responsiveness off the face while the back is finished with a custom milling process. While a traditional blade, offering a thin top line with maximum work-ability and trajectory control, it also provides a muscle back design to provide maximum distance. The MB is a player’s club, to be sure, but one that is of moderate face size, to induce confidence and forgiveness.

With a Tour Black PVD finish, the MB series is a coalescence of traditional looks and modern technology for a player seeking maximum feel and work-ability without sacrificing distance and forgiveness.
