Abstract

An iron style golf club head comprising a substantially perimeter weighted club head, including the interposing of three inserts, a striking face insert, a dampening insert and a back insert. The dampening insert, preferably made of a lead alloy, is interposed between the other inserts, and provides for changes in club swing weight while also providing relief for vibration and acoustical variations. The striking face insert is preferably made from a stainless steel alloy and the back inset is preferably made from a carbon graphite.

The dampening insert is maneuvered into varied positions to effect a change in the specific gravity of each club head of a golf club set.

Claims

1. A golf club head with improved weight distribution and vibration dampening, the golf club head comprising:

a body having a front portion defining a cavity therein;

a strike face insert, a dampening insert and a back insert disposed within the cavity, the dampening insert being located between the strike face insert and the back insert; and

,

wherein the dampening insert is made from a lead alloy.

2. The golf club head according to claim 1, wherein the strike face insert has a thickness in the range between about 0.07 to 0.11 inches.

3. The golf club head according to claim 1, wherein the strike face insert has a thickness of about 0.09 inches.
