Hello fellow civilians, survivors, etc! If you have noticed an issue where you are using a tool, and it doesn't seem to be working; For example, your axe isn't cutting trees, or your pickaxes aren't working on rocks, then this is because you have two of the same tool in your inventory. You will need to set aside the other duplicate tool, and proceed with only one on your person. If that doesn't solve the issue, then you are experiencing a separate bug.
Good luck, and have fun!
