Abstract: An improved set of golf club irons, wherein each golf club iron head has a structure for redistributing weight of the club towards the perimeter thereof, particularly in the rear cavity region. This is accomplished by increasing the volume of the cavity by using an undercut perimeter which permits weight redistribution for example to increase the thickness of the top line, the toe and the sole of the club head. However, the undercut portion of the invention is sealed from moisture, dirt and other potentially detrimental materials that might otherwise accumulate therein during play. Such sealing is accomplished by means of a low density insert which is preferably made of a low mass density material such as plastic, rubber, epoxy or low density metal material such as titanium or aluminum. An additional feature of the present invention comprises an aspect of the structure thereof which varies from club to club in a set of irons.
