A golf club iron having a head center of gravity that is low and forward enough to provide a better swing, good striking and swinging feel, and improved ball flight is disclosed. The iron has a recess in a leading edge region and a high density insert disposed within the recess to achieve the desired center of gravity location.

Technical innovation in the size, structure, configuration, material, construction, and performance of golf clubs has resulted in a variety of new products. Most irons are constructed in such a way that the head is made from a single type of parent material, such as steel. Some irons have discrete weighting elements incorporated into their structure, but these weights typically are incorporated into sole or perimeter regions located away from the face. As such, most irons currently available on the market do not have a center of gravity (CG) that is located low or forward enough in the head for the head to achieve optimum performance.

The irons of the present invention have high density leading edges and thus extremely low, forward centers of gravity and moderate loft/de-loft moments of inertia (Iyy). The graph 100 in FIG. 5 shows the center of gravity locations, mapped according to height and depth of the iron head frames, of 6-irons of the present invention and 6-irons currently available on the market. The circled region 110 in the graph indicates the center of gravity locations of irons designed according to the present invention, while the small circles represent Callaway irons and the small dashes represent non-Callaway irons. Center of gravity locations are generally obtainable by referring to the leading edge weights of the irons.
