The problem in the ISS with tools is that they don't stay in one place; they float around in microgravity. The challenge is that it is hard to keep them in one place when trying to use them to fix things. My tool is two screwdrivers and two wrenches; one small one and one big one of each. This tool helps to decrease the amount of time needed to grab tools. The tools are in a plus sign shape so the astronauts can just turn it and then they have a new tool. This tool helps so much with how time consuming it is when the astronauts have to grab tools that are floating around in space. Even if it does float away, they'll be grabbing four tools at the same time instead of having to reach for and find four different tools. The tool is easy to carry and portable because it is not heavy.
