a back face opposite the strike face; and
a first trench set at the back face;
wherein;
the club head comprises at least one of a wedge-type head or an iron-type head;
the first trench set comprises;
a first trench comprising;
first and second first-trench shallow portions;
first, second, and third first-trench deep portions;
a first trench centerline extending along a center of each of the first-trench shallow portions and of each of the first-trench deep portions;
a second trench comprising;
first and second second-trench shallow portions;
first, second, and third second-trench deep portions;
anda first rib between the first and second trenches;
the first first-trench shallow portion is;
bounded by both the first and second first-trench deep portions; and
shallower than each of the first and second first-trench deep portions;
the second first-trench shallow portion is;
bounded by both the second and third first-trench deep portions; and
shallower than each of the second and third first-trench deep portions;
the first rib comprises a first rib centerline parallel to the first trench centerline;
centerpoints of the first first-trench deep portion and of the first second-trench deep portion lie along a first line that perpendicularly intersects the first rib centerline; and
centerpoints of the second first-trench deep portion and of the second second-trench deep portion lie along a second line that perpendicularly intersects the first rib centerline.

4. A club head comprising:
-
a strike face; a back face opposite the strike face; a first trench set comprising a first trench and a second trench in the back face; and a loft plane of the strike face; wherein; the first trench comprises; a first shallow portion set comprising a plurality of first-trench shallow portions; and a first deep portion set comprising a plurality of first-trench deep portions; the plurality of first-trench deep portions are interleaved with the plurality of first-trench shallow portions; the plurality of first-trench shallow portions extends into the back face; the plurality of first-trench deep portions extend deeper into the back face than the plurality of first-trench shallow portions; the back face comprises a first rib between the first and second trenches; and the first rib comprises a wall that is substantially perpendicular to the loft plane. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A method for manufacturing a club head, the method comprising:
-
providing a strike face; providing a back face opposite the strike face; forming a first trench into the back face; wherein; the first trench comprises; a first shallow portion set comprising a plurality of first-trench shallow portions; and a first deep portion set comprising a plurality of first-trench deep portions; the plurality of first-trench deep portions are interleaved with the plurality of first-trench shallow portions; forming the first trench into the back face comprises; moving one of a first end mill or the back face relative to another one of the first end mill or the back face along a trench length for the first trench while; extending the first end mill a shallow distance into the back face to form the first shallow portion set; and extending the first end mill a deep distance into the back face to form the first deep portion set; and the deep distance is greater than the shallow distance such that the plurality of first-trench deep portions extend deeper into the back face than the plurality of first-trench shallow portions. - View Dependent Claims (20, 21, 22, 23)
