I took my little pen knife to school a couple times in grade school, but even in the 80s I had to hide it. Just took it in to show a friend. Now I’d probably be in violation of the patriot act somehow, that’s how serious they take it.
Same here. All of us had knives from the time we could think about bringing them. Only got one taken one time, and the teacher gave it back after class and told me, in short, “I’m not saying don’t bring it, but don’t let anyone see it outside of this class.”
