A golf club head includes a golf club head body, a striking plate mounted to a front side of the golf club head body, and a perimeter wall extending rearward along a perimeter of the golf club head body. At least one hole is defined in a toe of the perimeter wall to reduce the weight of the upper part of the golf club head body, thereby shifting the center of gravity of the golf club head downward toward the heel and thereby increasing the inertial moment of the golf club head.
