Did you make sure that the tools are not in use in any other way at the time (vehicle de-/construction or crafting for example)?
Adding a game version to your report would be helpful, as the game is updated multiple times a day and without knowing if this is an old and already fixed bug - or a bug at all - is turning support into a guessing game almost no one wants to play.
Assuming that your tools are not in use and this isn’t just some oversight, I think the amount of forum posts that this produced (topic 1, topic 2 & topic 3) justifies some deeper look.
Would you agree to upload your save file somewhere (google drive / dropbox / …) - if it isn’t a “tool in use” problem - so I can take a look at your setup and don’t have to go through the pain of trying to reproduce this behavior myself?
