I carry one around the farm and when I know I'm safe from going through metal detectors which are becoming ubiquitous here in Marylandistan. Swiss Army knife to be exact.

Bringing one into an elementary school would earn you a trip before a judge I'm afraid.

I carried a carbon steel bladed Case folder with bone scales in high school- not to be brandished on school grounds, but allowed. Others did similar, but the probable difference is that I still carry (and use) that very knife wherever I go that doesn't include airline travel. It still has nearly all the blade due to not letting it get dull and needing metal removed. Sixty four years now, and counting.
It is so pocket worn that the escutcheon on the side is rubbed away and to prove it is, indeed, a Case you need to open it and read the stamp on the blades.

I only need it when I go buy Fentanyl at the local homeless encampment.

The guys would play mumbly peg  by the school doors until the first bell rang to let us in. Mine was an Old Timer too.

Starting in 1st grade, we didn't have kindergarten, a Davy Crockett pocket knife and I think it only had one blade.  Mom & Dad gave me a J.C. Higgins single shot 22 for my 5th Christmas.  It's gotten worse.

Probably around 3rd or 4th grade the Davy Crockett knife was lost and to 'be like Dad' I graduated to a 3 blade Stockman.  That would be about 65 years ago.  I still carry one, either a Case or Uncle Henry.

Why a fella remembers some things I have no idea.  In junior high, back when that was 7th and 8th grade, our English teacher was trying to open something, what I don't remember, and she asked if anyone had a pocket knife.  Well, this was a little bitty farm town in the Ozarks and I think most of the boys in class produced various pocket knives.  'Course in high school if someone had shook down the cars and pickups in the parking lot you could have armed a couple platoons.

My oldest son graduated in 1991 with 29 kids in the graduating class.  Not the same town where I went to school but, things hadn't changed a lot.  I taught him to sharpen knives and he used to sharpen them for his classmates 50 cents a blade.

My how things have changed for the worse.

Been carry one for as long as I can remember.  First birthday in the mid 1950’s and have a few guns.  Actually bought my first gun, that my parents didn’t buy, when I was 11.  Set pins at my aunts bowling ally at 10 cents per line.

My very modest collection. That big ole Bowie knife is one heck of a knife. I'm sure I have more knives scattered around. Yep, there's one out in the plow truck.
