15 or so years ago we went to the St. Louis Arch and visited the museum of the Western Plains underneath. They had a metal detector, so I had to hand the park rangers my pocket knife. They checked the blade against a gauge taped to the counter to see if it was longer than 4". It was a Spyderco with a 3.75" blade, so they handed it back. I guess they would have busted me for having a concealed weapon if it were longer. That was 15 years ago, pre-9/11.
MS state law allows us to have up to a 4" blade on a folding knife, any longer than that and we're carrying a concealed dangerous weapon, unless we have a CCW permit. Swichblades are forbidden, there's not even a medical excuse clause, but spring assisted knives and knives with assisted opening is legal, which makes no sense, but that's the law. Thanks, Henry Fonda.
We're allowed to carry sheath knives of any sort while hunting or camping or at appropriate sporting events. Otherwise, we're not allowed to carry a "Bowie knife", "dirk" or "butcher knife" on our persons, but they don't have a legal definition of those things. Would I be busted with a chef's knife, since they're not carving knives? Swords aren't mentioned (other than sword canes), but I don't want to try my luck. They can't wait to use their shiny new Tasers on folks.
There's no regulations at all about pipe cleaners, rolling papers, or cigarette lighters. Propane refill cans are regulated because of huffing, same as crazy glue and spray paint. Walmart is all politically correct, they self-regulate certain air rifle and paintball gun items, anyone can buy bb's, pellets, and paintballs, but the guns and CO2 cartridges are for 16 and up.
A bright spot to it all is our high school has an archery team and the kids are allowed to bring their bows and arrows to the principal's office for practice.
I graduated HS in '88, back then, they had a designated smoking area outside where teachers and students both could smoke, if the student had a permission slip from their parents. It was that or keep having the toilets wrecked by students discarding their butts in the tank. When I was in middle school, the prinicipal would be preceded by a cloud of cigar smoke when he made the rounds. The teachers would smell him coming, so they would make sure we were at our best behavior in case he popped in for a visit.
Years ago, they hired a cop who had just moved here from California, he pulled his pistol on some kids and made them drop to the ground while he called for backup because one of them had a pocketknife. They fired him because he didn't know how things were done around here.
