Well I'm keeping pretty low profile with my knives. I try to not whip out my EDC fixed blade at every possible moment

.
My friends at the university know I'm carrying a knife and will ask for it occasionally and I don't make a big secret out of the fact. The knife is carried in a nice orange kydex sheath on my belt under my sweater, so occasionally someone sees it. But I haven't had bad experiences yet.
For the anecdotes: I'm not only EDCing a knife but a nice little AA Flashlight also.
I had one guy who just wouldn't get why I carried a flashlight... "What do you carry a flashlight for?" I just pointed my finger at the window.. Outside its winter, and dark after 5pm. "Because it's dark!"
He didn't quite get it...
