  • Patent number: 5398929
    Abstract: In construction of an iron-type golf club head provided with a face side shooting board, the shooting board is fitted into a recess formed in the face of a main body and an elastic intermediate is interposed between the shooting board and the recess. At shooting a ball, the shooting hoard is allowed to perform elastic displacement within the recess opposite to the direction of back-spin impartation to the ball, thereby mitigating ill influence of excessive back-spin and assuring good control on ball rolling on the field, in particular on a putting green.
