A golf club head includes a golf club head body having a toe and an engaging portion to which a striking plate is mounted, a hosel mounted to a side of the golf club head body, and a heel between the hosel and the engaging portion of the golf club head body. The heel includes a hole for reducing a weight of the heel, thereby shifting a center of gravity of the golf club head toward the toe of the golf club head body and increasing an inertial momentum of the golf club head.
