1. A binder clip comprised of:a. a first and a second wire arm, identical to one another and each having two ends, and, each bent into a planar U-shape, the planar U-shape, having three closed sides formed from the wire arms and, and a fourth, open side, of the planar U-shape, including the two ends of the wire arms bent towards one another forming two wire tabs pointing towards one another leaving a gap between the wire tabs, and,
b. a metal spring formed from an essentially rectangular sheet of metal having first and second edges, each parallel to one another, and, third and fourth edges, each parallel to one another and perpendicular to the first and second edges, and, the metal spring formed by bending the third and fourth edges of the rectangular sheet of metal towards each other to form a U-shaped spring, and, the first and second edges rolled to form a first and a second cylinder, each cylinder having two ends and an opening at each of the ends, and, the openings having an edge, and,
c. the two wire tabs of the first wire arm are inserted into the two ends of the first cylinder, one per end, and the two wire tabs of the second wire arm are inserted into the two ends of the second cylinder, one per end, and,
d. a flexible cover that fits over the planar U-shape of the first and second wire arms and the flat metal spring, and,
e. when the U-shapes of each of the two wire arms are moved apart, the flexible cover contacts the U-shaped spring and acts as a fulcrum, pressing against the U-shaped spring to pry open the U-shaped metal spring, separating the first and second cylinders for insertion of an item to be held in the clip that, when the U-shapes of the arms are released, the item is then held in place between the rolled edges.
