  • Patent number: 5380005
    Abstract: An iron golf club head has a hosel provided therein with a bore extending to reach the sole of the head. The striking blade of the head is provided at the rear end thereof with a tail seat extending to cover partially the bottom end of the bore. The hosel can be therefore shortened to an extent that the weight of the striking blade is increased and that the connection point of the shaft and the head is located at a level lower than the center of gravity of the striking blade, thereby resulting in an enhancement of the ball-striking effect of the head and in strengthening the fastening of the shaft with the head.
