ABSTRACT:
The staple remover includes a large and small arm cooperating to withdraw staples. The larger arm includes at a working end a pair of prongs between which is centered a single prong provided at a working end of the smaller arm. The prongs include curved camming surfaces extending from arm working ends toward their pivoted ends. Arms are interconnected at their pivoted ends so as to be opened and closed for cooperation when removing bound staples. The camming surface of the single prong of smaller arm is shorter than the camming surfaces of the prongs of the larger arm such that a staple will be deformed and discarded rather than clinging to remover prongs. Included within the arms is a collection box with a magnetized plate or drawer positioned for capturing the discarded staples. An opening in the collection box permits removal of the plate for crushed staple disposal.
