Claim:
A golf club exhibiting impact force dampening and ball directional characteristics upon impacting a golf ball, comprising: an elongated handle terminating in a three-dimensional shaped club head exhibiting a substantially smooth ball striking face with heel and toe mounting locations being disposed in spaced fashion relative to said ball striking face; a vibration inducing coiled spring exhibiting a half elliptical or circular shape and extending within an open interior of said club head between the heel and toe and in an opposite and generally inwardly spaced fashion relative to a depth extending contour of said club head; at least one special manufacturing set screw for mounting said vibration inducing spring at a selected one of the heel and toe locations; and upon impacting the golf ball, said vibration inducing spring responding to an off-center force applied to the ball striking face to increase an effective surface area of said striking face associated with straight travel of the ball.
