ABSTRACT:
This disclosure pertains to a pincer-like staple remover having a pair of elongated arms to which are affixed a pair of complementary jaws. The arms are biased to assume a divergent position relative to the interconnected ends thereof. The jaws are fabricated from a metallic material, each of which utilizes a pair of parallel spaced apart plates. A portion of the jaws, adjacent the staple grasping portions thereof, are fabricated from a non-magnetic plastic material and are bridged by a magnetic plate contacting the spaced apart non-metallic plates. Staples, freed from a grasping position to a paper or cardboard substrate, are magnetically attracted by the magnetic plate and are caused to reside between the non-magnetic plastic walls forming a staple storing cavity there-in-between. The magnetic plate may be slidably removed from its metal plate bridging position, so as to empty the cavity of accumulated staples.
