ABSTRACT:
An iron-type golf club includes a conventional-weight section, a lightweight section and a heavyweight section. The conventional-weight section includes the hitting face and at least a portion of the hosel. The heavyweight section, made of a denser material than the conventional-weight section, includes the sole and an optional back flange. The lightweight section, made of a material less dense than either of the other sections, includes a core to which the other two sections are secured, such as by co-molding the core to the other two sections. The heavyweight section includes anchoring structures to which the lightweight section can securely attach. This arrangement maintains the overall weight of the club head compared to a similarly proportioned conventional club head while shifting the center of gravity low and aft. As such, the club head provides benefits such as forgiveness for thin shots, heel/toe shots, and provides longer drives with less roll.
