Patent ID: 11247106

Abstract:
A club head with a variable face thickness includes a body having a toe, heel, sole, and top portion. The loft angle LA and the club head mass mh satisfy mh=2.1 g/degree*LA+a, where 190 g<a<210 g, and the club head has a blade length less than 80 mm. A striking face of the club head has a face center, and defines a face plane. A virtual center plane extends vertically through the face center perpendicularly to the face plane. A center of gravity of the club head is located not more than 2.0 mm from the virtual center plane, and a moment of inertia about a vertical axis extending through the center of gravity satisfies: Izz>mh*9.3 cm2. In one aspect, a face insert including the striking face has a mass mf such that mf/mh is less than or equal to 0.22.
