发明名称 Forged iron-type golf clubs
摘要 Forged cavity back iron-type clubs and oversize clubs are disclosed. These forged clubs have thin, durable hitting face and relatively large cavity volumes. These clubs have high rotational moments of inertia to minimize distance and accuracy penalties associated with off-center hits. Long irons with hitting face of about 0.100 inch thick are achievable by the present invention. Also disclosed are forged irons made from stainless steels and annealed to achieve the desired hardness and ductility.
