[post_page_title]Paper clips[/post_page_title]
The design of the original metal paper clip is something we’ve wondered about, since papers can be held together with other things besides metal wires.
The double oval shape, which goes back to the late 1800s, was chosen because of its non-skid design. It would also hold the papers securely, while laying relatively flat in between stacks of papers. Because of its usefulness, this is still known as the “universal” paper-clip, even though there are many different designs available today.
