My tool allows astronauts to be able to unscrew, and take out nails, without damaging them and without using multiple tools. You program the tool to whatever you need, and the nozzle of the tool rotates it back and puts it in a removable box that you can then get the little pieces out again, and with this tool it allows you to reuse the material over and over again.
