Bunch of weenies is correct. My parents gave me a Cub Scout multi-bladed pocket knife on my 8th birthday. I have carried a knife in my pocket virtually every day of the 47 years since, including all through school. Nobody cared.
I also on many days brought my .22 rifle to school on the bus and kept it in my locker all day until getting on my friend's bus and going to his farm to shoot woodchucks after school. Nobody cared. Nobody ever got shot or cut.
We've become a nation of sheep. Baaaaaaa.
My grandfather gave me a pocket knife when I was a relatively little kid and told me to always carry it. While that knife is long gone, I've always carried a knife (and where I'm allowed, a gun).
41 years later I still have it, plus about 100 others and I carry one everyday. I have a "travel" knife with a ceramic blade and kevlar body. Never been stopped by a metal detector so far.
I too, carry a gun everywhere that is "legal". I guess the use of the term "legal" proves just how bad it has gotten. I am ashamed of myself having to use that term.
