Abstract
A golf club of the iron type has a metal head with a front striking face and a slot spaced rearwardly from the striking face to provide a flexible and resilient striking plate. The thickness of the plate is such that the plate will: (a) resiliently flex and store energy when the striking face impacts a golf ball; (b) return to its original position to transfer energy to the ball as the ball leaves the striking surface; and (c) not deflect to such an extent that golf balls hit off center on the plate will be dispersed excessively from the intended line of flight
