People shouldn't worry about carrying and using larger knives, as long as they don't do it with a bad attitude. If you carry a large knife for in-your-face shock value, then that ain't good, but if you just pull it out and use it when you need it, then there's nothing wrong with that.
Carrying a knife is, literally, abnormal behavior. Most people don't carry knives and the ones who do are in a small minority. It's up to the knife carriers to convince the non-knife people that there's nothing wrong with what they're doing.
That's why I don't like the term "sheeple". It's a standoffish insult that dismisses those who don't share our views. It creates an "us vs. them" mindset that's counterproductive.
If you carry a large knife with a good attitude though, you might be suprised at what you can get away with.
I remember James Mattis writing about how he carried a Vaquero Grande. That's easily one of the scariest looking knives out there. He used it openly and was actually able to convince some old ladies at his synagogue to use it to cut bread!
I think that, to at least some degree, people react more to your attitude than the knife. If someone says, "Whoa... what do you need
that thing for, OJ?" when you pull out your knife, you can respond in a couple of different ways. You could get all defensive, make a smart-ass comment, or just flee to the nearest internet knife forum and whine: "Those stupid sheeple! They're idiots!". Or, you could respond by smiling and talking to them, and at least try to gently reassure them. How you act makes a big difference in how people will interpret the event.
Sheeple friendly not necessarily because of its size, but because it's a classy gents folder.
