A tool is provided for bending wire for use in earrings. The tool has a two handles; an anvil plate; two terraced floating bars; two forming links, each having a stanchion projecting therefrom and a forming link rod projecting from the first forming link; an upper and lower linkage arm; a translating pin; and a planetary gear having an eccentric forming rod projecting from its lower face. The anvil plate has a longitudinal slot and arcuate minor and major forming slots formed therethrough; a circumferential gear formed on one side of the anvil plate, adjacent and exterior to the major forming slot, spanning less than 360°; and a retaining wall and a forming anvil formed on the other side of the anvil plate. The handles are pivotally joined to the anvil plate such that the forming link rod and a stanchion engage a wire lying against the retaining wall.
