There are too many tools for astronauts to be carrying around; screwdrivers, wrenches, hammers, rulers, electricity-meters, etc. It just seems like too many to keep track of. So this tool combines 2 or more of those tools (depending how many screwdrivers and wrenches they use). This tool combines an adjustable wrench head and a screw off screwdriver head with removable bits (bits not included) on the other side with a compartment in the handle to store other bits for the screwdriver attachment.
