Just be sure to leave them in your car when you go to the courthouse or airport............I have more of a problem with losing pocket knives -but I've never thrown one away.
By the way - Both my girls grew up having a small folding knife from the time they were old enough to trusted with one and now always carry one in their purse. Hence the "need to have a welcome to family" pocket knife.
Now flashlights, those are essential items and you can't have too many!
