Abstract
A novel golf club includes an elongated metal shaft and a metal club head secured to a lower end portion thereof. The club head comprises an integrally molded body having a hollow interior with an opening outwardly onto a planar front face. A plurality of metal face plates, each having a planar back face with an outer periphery matching the periphery of the front face of the club head body are adapted to be mounted on the body closing off the hollow opening thereof and secured in place with fasteners. Each face plate includes a ball engaging outer face having a set of characteristics comprising a curved bulge from toe to heel, a curved roll from bottom to top and a degree of angular loft relative to a bottom edge, and at least one of the characteristics of a selected face plate is different from that of the other(s) to impart a different path to a ball when struck thereby. The top and bottom walls, and the toe and heel portions of the club head taper from a minimum thickness rearwardly of the front face to a maximum thickness at the front face around the hollow opening.
