FWIW, my school in the early 90s was zero tolerance on guns. I lived in a semi-rural area, and every year around hunting season a couple kids would be suspended/expelled for having a rifle in the rack in their truck (yes, they checked the parking lot). School also got real slow for the first week of hunting season.
Knives were a different story though. As a somewhat nerdy kid, I kept a Swiss Army knife in my pocket for most of high school. I tightened up a lot of loose bolts on chairs/desks/tables in my time there. Teachers knew I had the knife, but folding blade knives were not considered a threat. Fixed knives (Bowie knives) would be confiscated and returned after school with a warning though.
I’m guessing knives are probably verboten as well these days.
