Abstract

A ground stake for securing ropes or other fastening elements comprises a head portion with an elevated, textured surface and two or more extending flanges above a neck portion comprising recesses and a passageway. A plurality of elongated fins, at least a portion of which are tapered, depend from the base of the head portion and terminate in a truncated blunt end, providing a stronger tip while allowing clean penetration of the ground. One or more of the fins may comprise a stiffening rib to increase the rigidity of the fin. The elevated, textured surface provides increased impact resistance and prevents slippage of a pounding implement when the stake is being driven into the ground.
