Abstract: A post for ground insertion having a plate which swings outwardly from the post upon upward movement of the post to prevent post extraction. An inclined surface of the plate is acted upon by earthen material for plate deployment. A limit stop positions the plate substantially perpendicular to the post. The plate may consist of overlapped plate members to provide a rigid or non-bendable portion. A bendable portion of the plate bends during upward movement of the post during setting of the post. Such bending occurs about perpendicularly oriented axes.

Abstract: A tool having a pivoted handle which intermittently retracts a sleeve to close jaws within the sleeve into wire engagement for wire retraction. The wire so tensioned is incrementally advanced axially into a wire retainer assembly and past retainer jaws which admit the wire and hold same against high tension loads. A manual control permits disengagement of the tool retainer jaws from the wire, after wire securement to a support, to enable axial disengagement of the tool from a length of tensioned wire. Methods are disclosed for tensioning and joining two lengths of wire using the present tool. Wire coiling tools are disclosed facilitating the practice of the methods.
