ABSTRACT:
A device for removing staples from papers, cloth, or other material without tearing or mutilating the material. The device utilizes a heel of palm to finger gripping action to facilitate a more natural action for removing staples. Staples are extracted by way of a jaw which opposes a wedge-shaped piece to an abutting plate piece, which straightens the staple while simultaneously pulling it out of the paper in a perpendicular direction. The wedge-shaped piece includes a portion where its width and thickness increase to dimensions wherein the sum of the width plus twice the thickness exceeds the slightly less than the total length of the three sides of the staples being removed, thus facilitating complete extraction. The device is readily incorporated into a standard stapler, so that both staple insertion and staple removing functionality are readily incorporated within a single device.
