Staple remover
The following method reduces the risk of damage to the paper sheets being separated, albeit at some cost to speed and associated time efficiency: Proper for pen style remover:[1] The design is focused on functionality and robustness with no unnecessary decoration (unless one includes the ergonomics of the handle) and minimised number of parts to lower costs and production time.They are made of chrome-plated steel, which is harder than the thin ductile wire of the staple and strong enough to withstand the force required to remove it.Though the blade is made from what was originally sheet metal, the right angles and clean edges mean that a punch and die method of production would not be suitable.The spring is made of chrome-plated steel, which is used because there is a point of minimum stress where continued use (opening and closing the staple remover) will not cause failure through fatigue.The supplier normally runs specialised machinery that is capable of producing large amounts of products at a high rate for a low cost.[2] A modified version, also capable of removing broken staples, was patented by Joseph A. Foitle of Overland Park, Kansas, but does not see widespread use, despite overcoming several disadvantages of the former device by a simple, yet novel and inventive, modification.
