NASA TECH BRIEF
Brief 63-10292 
This NASA Tech Brief is issued by the Technology Utilization Division to acquaint industry 
with the technical content of an innovation derived from the NASA space program. 
Heavy-Duty Staple Remover Operated By Hand 
The problem: Large, heavy-duty wire staples are 
difficult to extract with commercially available staple 
removers. Considerable time can be lost in the process 
of extracting staples from thick documents because 
the lower extremities of the heavy staples must usually 
be straightened (e.g., with pliers) before employing a 
commercial manually operated staple remover. 
The solution: A heavy-duty hand tool, which re-
quires only one simple operation to extract the staple, 
without damaging the surface material. 
How it's done: The wedge-shaped rooter is slid 
under the staple to be removed, and the handle of the 
device is squeezed down until the staple is completely 
extracted. In the process of extraction, the sides of the 
staple are pulled upward by the bending hook, while 
the top central portion of the staple is held down by
the post, as shown in the enlarged view. This bending 
action facilitates one-step extraction of long staples 
with a minimum exertion of force on the handle, 
which provides a large mechanical advantage as a 
lever arm. 
Note: 
This staple remover (an original design by the Jet 
Propulsion Laboratory) easily removes staples from 
one-inch-thick reports and is especially effective for 
removing round-headed staples from packing crates. 
Patent status: NASA encourages commercial use 
of this innovation. No patent action is contemplated.
