Claim:
A golf club head comprising: a body comprising; a crown portion, a sole portion, a heel portion, a toe portion, a rear portion, a front portion comprising a club face, and a geometric center; and a protrusion weight protruded from the body; wherein: if the body comprises a skirt portion, the protrusion weight protrudes from the heel portion and at least one of the sole portion or the skirt portion of the body; if the body lacks the skirt portion, the protrusion weight protrudes from the heel portion and the sole portion of the body; a center of gravity of the golf club head is defined by both a mass of the body and a mass of the protrusion weight; a center of gravity of the body is defined by the mass of the body independent of the mass of the protrusion weight; a center of gravity of the protrusion weight is defined by the mass of the protrusion weight independent of the mass of the body, and is external to a body volume of the body of the golf club head; a moment of inertia of the golf club head is increased due to a distance extension of a distance between the center of gravity of the protrusion weight and the center of gravity of the golf club head, the distance extension being external to the body volume; the center of gravity of the golf club head is located at the heel portion of the body, shifted by the protrusion weight away from the toe portion and away from the center of gravity of the body; and the protrusion weight is at least partially visible from an exterior of the golf club head.
