Abstract
Abstract A golf club in the form of a sand wedge constructed with a relatively wide sole from the front edge to the rear edge with a plurality of spaced fingers extending upwardly and rearwardly therefrom which are separated and slanted for elevating the ball. The underside of the fingers converge inwardly to form a generally V-shaped finger which immediately increases the space between the fingers inwardly of the front face thereof thereby reducing resistance and friction of sand or other material passing between the fingers during the golf swing. The ball contacting surface of the fingers is slightly rounded or convex transversely which together with the space between the fingers reduces to a minimum the buffering and shock absorbing affect of the sand between the club face and the ball thereby allowing immediate and effective contact between the club face and the ball. The club face may be flat or concave which allows for a wider controlled range of elevation of the ball.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
275 words
A golf club head of the sand wedge type comprising a sole having a leading edge and a trailing edge extending from the heel to the toe of the club head and defined by a top surface and a bottom surface, upwardly extending shank means rigid with the heel of said sole for connection with a club shaft, a plurality of upwardly and rearwardly inclined fingers rigid with the top surface of the sole, said fingers being elongated and disposed in spaced relation to each other, each of said fingers having a top surface defined by a leading lower edge and a trailing upper edge, the top surfaces of the fingers defining a striking face from their leading lower edges to their trailing upper edges, each of said fingers having an undersurface extending downwardly and forwardly from the trailing upper edges of the fingers and merging with the trailing edge of the sole and defining a trailing face on the club head, the space between the fingers providing passages from the striking face of the club head to the trailing face thereof for passage of sand or material therethrough to enable contact between the striking face and ball, said sole being smoothly convexly curved in a shallow curve from the leading edge to the trailing edge along its bottom surface and smoothly convexly curved in a shallow curve from the toe to the heel along its bottom surface, the sole having a relatively thin vertical dimension, the leading lower edges of said fingers extending forwardly beyond the leading edge of the sole and defining a leading edge for the striking face of the club head.
Claim 2
Dependent Claim
