<p>This invention is an improved set of golf club cavity backed irons, wherein each golf club iron head has a structure for increasing the volume of the cavity (28) using an undercut perimeter which permits weight redistribution to increase the thickness of the top line (16), the toe (20), and the sole (18) of the club head. The undercut portion of the invention is sealed from moisture by means of a low mass density insert (30) wherein the insert is made of a low mass density material which addable serves the function of dampening sound and vibration upon ball impact. A weight slot (32) is used to vary the location of the center of gravity between the toe (20) and the heel (22) as a function of the loft of the club to provide maximum accuracy of trajectory and ball hitting capability.</p> |
