Abstract
Golf club heads with improved aerodynamic properties. In an example, the golf club head has striking face; a sole connected to a bottom side of the striking face; a crown connected to a top side of the striking face. An aft slice of the golf club head includes a rearmost point, a toe-side aft slice on a toe side of the rearmost point, and a heel-side aft slice on a heel side of the rearmost point. The heel-side aft slice has a volume greater than a volume of the toe-side aft slice. The aft slice is defined as a portion of the golf club head to a rear of a slice line and between an outer perimeter of the golf club head and an offset perimeter slice curve.

A metal-wood type golf club head comprising:
- a striking face defining a frontmost point of the golf club head;
- a sole connected to a bottom side of the striking face;
- and
- a crown connected to a top side of the striking face,
- wherein an aft slice of the golf club head is defined as a portion of the golf club head to a rear of a slice line and between an outer perimeter of a rear portion of the golf club head and an offset perimeter slice curve having a shape corresponding to a shape of the outer perimeter of the rear portion of the golf club head, and
- wherein:
- the slice line extends in a heel-to-toe direction and is located a slice depth rearward from the frontmost point, the slice depth being equal to 60% of a front-to-back length of the golf club head;
- the offset perimeter slice curve is offset from the outer perimeter of the rear portion of the golf club head by a perimeter offset distance of 1 inch;
- the aft slice includes a rearmost point, a toe-side aft slice defined as a portion of the aft slice on the toe side of the rearmost point, and a heel-side aft slice defined as a portion of the aft slice on the heel side of the rearmost point;
- a volume of the heel-side aft slice is at least 15% greater than a volume of the toe-side aft slice;
- the aft slice defines a first area in a first cross-sectional plane perpendicular to the heel-to-toe direction and offset toe-ward from the rearmost point by 5 mm;
- and
- the aft slice defines a second area, greater than the first area, in a second cross-sectional plane perpendicular to the heel-to-toe direction and offset heel-ward from the rearmost point by 5 mm.
A metal-wood type golf club head comprising:
- a striking face defining a frontmost point of the golf club head;
- a sole connected to a bottom side of the striking face;
- a crown connected to a top side of the striking face;
- and
- wherein an aft slice of the golf club head is defined as a portion of the golf club head to a rear of a slice line and between an outer perimeter of a rear portion of the golf club head and an offset perimeter slice curve having a shape corresponding to a shape of the outer perimeter of the rear portion of the golf club head, wherein:
- the slice line extends in a heel-to-toe direction and is located a slice depth rearward from the frontmost point, the slice depth being equal to 60% of a front-to-back length of the golf club head;
- the offset perimeter slice curve is offset from the outer perimeter of the rear portion of the golf club head by a perimeter offset distance of 1 inch;
- and
- the aft slice includes a rearmost point, a heel-side interior-most point, and a toe-side interior-most point, the golf club head being configured such that, when arranged in an address position on a ground plane, the toe-side interior-most point is positioned higher above the ground plane than the heel-side interior-most point by an asymmetrical distance that is at least 10% of a height of the golf club head.
