(ii) a deck member disposed at a distal end of the body and defining a deck surface having a deck surface centerline that surrounds the longitudinal axis, wherein the deck surface includes:
(A) a first deck surface portion extending along a first angular range of the deck surface about the longitudinal axis, wherein the first deck surface portion is wholly positioned within a first deck plane,
(B) a second deck surface portion extending along a second angular range of the deck surface about the longitudinal axis, wherein the second deck surface portion includes a linear shape and is wholly positioned within a second deck plane,
(C) a first array of staple openings disposed on the first deck surface portion and arranged in a first orientation relative to the deck surface centerline, and
(D) a second array of staple openings disposed on the second deck surface portion and arranged in a second orientation relative to the deck surface centerline, wherein the second orientation is different than the first orientation, and
