The astronauts work in very big bulky suits with big gloves. Some tools might melt in space. ABS plastic has no true melting point, but is usually printed at 230o fahrenheit. ABS plastic won’t melt in space. Tools will float away if not tethered. Some astronauts forget tools because they have so many. My tool is a hammer with a big handle. At the end of the handle there is a wire cutter. There is no assembly of my tool. Hold onto the handle and use it like a normal hammer. For the wire cutter hold the tool the other way around. Put pressure on the wire against the cutter. There is a hole in the middle of the handle so that the tool can be tethered. My tool combines two tools so the astronauts won’t forget their tools because they will have less to worry about. My tool is awesome.
