1. A golf club head comprising:
a toe end, a heel end, a top rail, a sole, a strike face, and a rear portion;
a body comprising a face panel;
an insert comprising an enclosed portion and an exposed portion;
wherein:
the body defines an interior cavity that is bounded by the face panel, the heel end, the top rail, the sole, and the rear portion;
the body is formed from a metal and the insert is formed from a non-metal;
the body defines an opening at the toe end of the golf club head;
the interior cavity is configured to receive the insert such that the enclosed portion fits inside the interior cavity and the exposed portion forms the toe end of the golf club head; and
an entire outermost surface of the toe end is formed entirely by the insert;
wherein the insert further comprises a backstop protruding from a surface of the insert;
wherein the backstop comprises a shape comprising a top side, a toe side, and a heel side;
wherein
the top side is convex and the toe side and the heel side are concave with respect to a geometric center reference axis;
the toe side and the heel side come to a rounded point at a bottom of the backstop;
the toe side and the heel side intersect the top side to form a pair of wing shapes that point towards the toe end and the heel end; and
wherein the shape facilitates temporary limit bending of the strike face at a region where the face panel is predisposed to flex more than desired, and the backstop located behind the face panel prevents over flexing of the face panel during a golf ball impact.
