The Space Screwdriver optimizes efficiency using the same technology as an everyday ratchet. This device allows the user to drive screws faster than traditional screwdrivers. It allows the user to fluently drive screws and eliminates the need to retract their hand after every revolution. It is ergonomically designed to prevent excessive work. The device is also very compact which is essential when operating in space. It is also easy to assemble using the three dimensional printer now located on the International Space Station.
