The tool you need

Description: This tool that I have created is a hammer that is also a screw driver. This tool can help astronauts for they won’t have to carry many tools. My invention can be helped because you may need a hammer then when you’re done you might need a screw driver as well so this tool will be more handy. This tool could be more improved and better than any hammer and screw driver we already have on earth today.
