ABSTRACT:
The method of making a paper clip to secure a plurality of sheets of paper together which are located in a stacked relationship. The paper clip produced by the method of this invention comprises a rigid sheet material metallic or composite body which is bendable and when bent, remains in the bent position. The method includes placing the overall configuration of the paper clip on the exterior planar surface of a thin sheet of metal or composite with the configuration of the paper clip including a pair of spaced-apart, normally triangularly shaped wings. Severing the exterior edges of the wings from the sheet of metal. Partially deflecting of the wings from the sheet of metal to a canted position relative to the sheet of metal and with the further possibility of deflecting of the wings by forcing the wings to a side by side relationship with the remaining body of the paper clip. Severing the remaining exterior edge of the paper clip and removing of the paper clip from the sheet of metal.
