A staple remover (also known as a staple decleater, staple puller, destapler, butterfly or crimper) is a device that allows for the quick removal of a staplefrom a material without causing damage. Although a simple metal wedge can be used, this method tends to tear fragile papers. For light gauge staples, many people instead use a device consisting of two opposing wedges on a pivot. For convenience, this device has a spring that returns it to the open position after use.

Some staplers, mainly small ones that are about 1.5 inches (3.8 cm) long contain an integrated staple remover. This is basically a piece of metal that is slid under each "curled" side of the staple and turned to loosen the staple.

A standard staple remover is constructed of just five distinct components:

• two plastic grips
• torsion spring
• two sets of metal swinging wedges (i.e., the blades)
• metal pin axle
• two smaller pins

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. The device works with a pincer action to unfold and pull out a staple in one motion.
