<p>The base member (1) is pivotally connected to the lever member (2) by a pin (5) that provides a leverage fulcrum point. The tongue (3) extends from the front end of the base member (1) and is used to wedge under the staple crossbar (11). The teeth (4) extends from the front end of the lever member (2). The user then lifts the lever member (2) into a second position so that the wider top section (8) of teeth (4) lifts the staple (10) from the substrate. The front edges (9)) of teeth (4) are curved such that it does not go below the baseline of base member (1), and thus do not interfere with or damage the substrate. The base member (1) presses against substrate providing support and allows the leverage operation to be performed on pliable and flexible substrates such as sheets of paper, and minimizes damage to the substrate.</p> |
