  • Patent number: 6224035
    Abstract: A simple and novel device to remove staple from sheet binding stack of papers comprising of a thin blade having two serrated notches formed by inner 1 and outer members 9 and 10 has been designed. A thin inner blade member is adopted to go beneath the bridge 3 of the staple, lift the legs 7 and 8 of staple out of paper and exposing them for firmly grasping in the two notches 5 and 6 during removal of the staple. The predetermined notches and cross sectional shapes of inner and outer members help to grasp and entangle the leg of the staple and does not allow it to slip and break during removal. The grip provided by the notch and in combination with leverage provided by the inner member by lifting one side of the leg of the staple at a time results in less pin breakage, less slippage and easy removal.
