Golf club head
An iron-type golf club head comprising a topline, a sole in opposed relation to the topline, and a front portion extending from the topline toward the sole. The front portion includes a leading edge, a substantially planar hitting region including a face center, and a peripheral region. The peripheral region at least partially surrounds the hitting region such that the hitting region and the peripheral region define therebetween a visually-recognizable hitting region boundary line including a sole-proximate boundary line segment such that when the club head is oriented in a reference position relative to a virtual ground plane, and in a virtual vertical plane perpendicular to the hitting region and passing through the face center, the sole-proximate boundary line segment is vertically spaced above the leading edge by a distance D 1 that is no less than 2.5 mm.
1. An iron-type golf club head that, when oriented in a reference position relative to a virtual ground plane, comprises:
a topline;
a sole; and
a front portion extending from the topline toward the sole, the front portion including a leading edge and a substantially planar striking face having a face center,
wherein, in a virtual vertical plane perpendicular to the striking face and passing through the face center:
the leading edge is vertically spaced above the virtual ground plane by a distance D 2 no less than 4 mm and no greater than 12 mm;
the sole comprises a sole length between 0.5 in and 1.2 in; and
the sole varies in camber in the front to rear direction.
2. The golf club head of claim 1 , wherein, in the virtual vertical plane, the distance D 2 is no less than 7 mm.
3. The golf club head of claim 1 , wherein, in the virtual vertical plane, the sole varies in camber such that radius of curvature decreases forwardly.
4. The golf club head of claim 1 , wherein, in the virtual vertical plane, the sole varies in camber between a first radius curvature associated with a first sole location and a second radius of curvature associated with a second sole location forward of the first sole location, wherein the first radius of curvature is greater than the second radius of curvature by a difference of at least 0.5 in.
5. The golf club head of claim 4 , wherein the difference between the first radius of curvature and the second radius of curvature is at least 1.0 in.
6. The golf club head of claim 4 , wherein the first radius of curvature is no less than 4 in.
7. The golf club head of claim 1 , further comprising a loft no less than 40 degrees.
8. The golf club head of claim 1 , wherein the sole portion is structured to contact the virtual ground plane at a sole contact location heel-ward of the face center by no less than 2 mm.
9. The golf club head of claim 8 , wherein the sole contact location is heel-ward of the face center by no less than 4 mm.
10. The golf club head of claim 1 , wherein the striking face further comprises a plurality of scorelines and a plurality of texture ridges.
11. The golf club head of claim 1 , wherein the striking face further comprises a plurality of scorelines and a plurality of face grooves.
12. An iron-type golf club head that, when oriented in a reference position relative to a virtual ground plane, comprises:
a topline;
a sole; and
a front portion extending from the topline toward the sole, the front portion including a leading edge and a substantially planar striking face having a face center,
wherein, in a virtual vertical plane perpendicular to the striking face and passing through the face center:
the leading edge is vertically spaced above the virtual ground plane by a distance D 2 no less than 4 mm and no greater than 12 mm; and
the sole varies in camber such that radius of curvature decreases from a first radius of curvature associated with a first sole location to a second radius of curvature associated with a second sole location that is forward of the first sole location, wherein the first radius of curvature is greater than the second radius of curvature by a difference of at least 0.5 in.
13. The golf club head of claim 12 , wherein, in the virtual vertical plane, the distance D 2 is no less than 7 mm.
14. The golf club head of claim 12 , wherein the difference between the first radius of curvature and the second radius of curvature is at least 1.0 in.
15. The golf club head of claim 12 , further comprising a loft no less than 40 degrees.
16. The golf club head of claim 12 , wherein the first radius of curvature is no less than 4 in.
17. The golf club head of claim 12 , wherein the sole portion is structured to contact the virtual ground plane at a sole contact location heel-ward of the face center by no less than 2 mm.
18. The golf club head of claim 17 , wherein the sole contact location is heel-ward of the face center by no less than 4 mm.
