The method includes supporting a first plate (236) having an outer surface (242) that defines a plane; cutting said outer surface (242) with a material-cutting beam (231) of a laser (234) along a predetermined curved profile to cut a cavity (240) into said outer surface (242) of said first plate (236), said predetermined curved profile being generally hook-shaped, and positioning a second plate adjacent said outer surface (242) of said first plate (236), said second plate providing a side wall surface for each of said cavities (240) of said first plate (236). A hook product includes a stem portion integrally molded with and extending from a sheet-form base to a distal end, the stem portion having a planar side, and a crook portion extending from the distal end of the stem portion to overhand the sheet-form base in an overhang direction, the crook portion having a flat planar side co-planar with the planar side of the stem, and an upper surface extending upwards form an upper extent of the planar side of the crook portion to an apex.
