| 1. A method of clamping paper in a paper clip having spaced first and second opposed surfaces, each first and second opposed
surface having a forward and rear edge, and connected together, at said rear edge, and a cam member having a tab at one end
thereof and a cam surface at another end thereof comprising the steps of:
(a) moving said tab to a first open position where said cam surface is displaced away from said first surface;
(b) inserting said paper through said forward edge between the said first and second opposed surfaces;
(c) moving said tab to a closed position whereby said cam surface is displaced towards said first surface to clamp said paper
between said cam surface and said second opposed surface;
(d) wherein said cam surface is rotatably and pivotally moved between said open and closed positions;
(e) wherein said first and second opposed surfaces and said cam member are comprised of resiliently deformable material for
accommodating different thickness of paper when said cam surface is moved from said open to said closed positions;
(f) wherein said first and second opposed surfaces comprises a bent wire which deforms when said cam member moves from said
open to said closed position so as to clamp said paper between said cam surface and said bent wire.
