The Hamdriver is a multipurpose tool that combines a Screwdriver and a Hammer. This tool can be used to remove or "drive" screws in or out of surfaces within the I.S.S (International Space Station) with both of it's sides. The reason why this tool is unique is because Screwdrivers are a well-needed tool onboard the I.S.S. In fact, astronauts practicing with toolboxes similar to those on the I.S.S have shown pictures of many different tools within the toolbox, including various Screwdrivers. Meanwhile, the Hammer is a uncommon tool onboard the I.S.S, and this tool allows the Hammer to be light weight and useable with one of the most common tools on the Space Station.
