Abstract
A single paper clip is capable of separately holding two different sheafs of papers. It is formed of a continuous length of wire successively bent into a series of re-entrant loops interspersed with six legs. One sheaf of papers may be secured between a first and third loop, and a second sheaf is thereafter secured between a third and fifth loop.
