These tongs are a simple and space-saving tool that are also functional as wrenches in four different sizes. To assemble, simply turn one piece over, and insert the pole into the hole in the other piece to create a rotating axis. The textured side of one piece gives it a better grip on more objects. These tongs will be incredibly useful to astronauts on the International Space Station, as they can eliminate the need to carry so many tools at once. These can be crucial to assembly, as they can help pick apart different parts with the tongs and assemble, disassemble, or re-assemble many different things with the use of four different wrenches. To use the wrenches, it is recommended that the astronauts temporarily disassemble the tongs to make it easier to work with.
