Im in rural Iowa, probably half the fellas from age 16-80 carry a knife (and you’d be surprised how many men AND women legally carry a handgun), but if you pay attention, this is a “Buck state”lol. 110s and 100 series fixed blades are so common, nobody (including LE) bats an eye at them, even the 119, that has a blade beyond the legal limit.
Because of that, you will get looked at funny if you pop open a flipper, assisted, and especially an automatic. I suppose it’s a familiarity thing. Some knives are scary looking, and some aren’t.
I’m rambling, but what I’m getting at is that I think the reaction you get definitely depends on what part of the country you’re in. My Buck 110 would fit right in at the sale barn coffee shop, but if some old boy noticed a me using a foreign looking PM2, he’d ask me what kinda weird looking knife I was using...and if I went to the city, a knife on my belt would draw way more attention than one clipped to my pocket.
