Title: Flattened round end staple

Abstract: A staple for attaching drop-wire molding or the like to a telephone pole is provided. To provide strength and easy, true driving action, a straight bight portion and mediate portions of perpendicular tines have opposed flat surfaces which intersect opposed rounded surfaces. Tapering tine tongues are partly defined by inner flat surfaces which intersect the outer surfaces in the same plane as the extended outer flat surfaces of the tine mediate and tine tongue portions. To encourage staple retention, ratchet-like teeth are formed on the outer tine tongue surfaces.
