I came up with this idea this morning while playing the server.
I thought that when you break a tool, such as the miner for example, it should stay broken even if you inventory it. This would make it so that when your tool breaks, it's actually required that you fix it at some point. Maybe have it set so that when it breaks you must install a couple spare parts in order for it to become working again.
To prevent people from just picking their tool back up and placing it down again and it being 100% fixed, it could be inventoried as "Broken Sonic Miner" or something like that.
Could this be done on other tools? Such as the radar, FM radio, etc. I thought it would be an awesome idea.
