Golf club head

A golf club head that, when oriented in a reference position, comprises:

• a striking face having a face center, a leading edge, and a virtual striking face plane generally parallel to the striking face;
• a sole portion;
• a top portion;
• a rear portion;
• a loft L no less than 40°;
• a virtual vertical plane perpendicular to the striking face plane and passing through the face center;
• a club head center of gravity spaced from the virtual vertical plane in a heel-to-toe direction by a distance D1 that is no greater than 6.0 mm;
• a hosel comprising a virtual hosel axis and an internal bore configured to receive a golf club shaft, the internal bore including a peripheral side wall and a shaft abutment surface configured to abut a tip end of the golf club shaft, the hosel further comprising an auxiliary recess extending sole-ward from the abutment surface of the internal bore;
• and
• a point P1 located at an intersection of the leading edge and the virtual vertical plane, wherein the center of gravity is vertically spaced from the point P1 by a distance D3 that is no greater than 17 mm,
• wherein the club head comprises a blade-type golf club head comprising an upper blade portion having a substantially uniform thickness and a lower muscle portion.
