A one-piece sheet metal fish hook comprises a member which derives much of its strength from the unique formations of the sheet metal stock. The member has a shank portion, a bill portion connected to one end of the shank portion, and an eye portion connected to the other end of the shank portion. The metal is formed to provide layers or laminations which shape the eye portion, such layers having one set of corresponding edges that are joined by a tight fold. The shank and bill portions are partly of channel cross section and partly of layered or laminated cross section, the latter having corresponding edges which are integrally joined to each other by a tight fold of the metal. The various formations provide for different degrees of strength and rigidity, at desired places.
