Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
116 words
A golf club head comprising a body and a throat adapted for connection to a shaft, the body and the throat being of unitary construction and the body defining a strike face for the head, the body and the throat being constructed of a plurality of wooden laminations and a plurality of resin impregnated fiber layers disposed between the wood laminations and securing the wood laminations to each other, opposing surfaces of adjoining wood laminations defining a plurality of interlocking tongues-and-grooves extending generally in the direction substantially parallel to the strike face and distributed across the opposing wood lamination surfaces from an edge of the laminations proximate the strike face to another edge of the laminations.
Claim 2
Dependent Claim
