I wear mine frequently (except in really hot weather when I'll be outside a lot because the leather can cause irritation under the sock for some reason) and the worst problem I've had was when a decorative thistle on the handle ripped a hole in my sock.

Seriously, I make sure not to wear it at sensitive locations such as an airport or government building. It's just as easy to slip it out of my sock and into the glove box in the car before I go in.

Even when I'm at a big public event (such as Pride in June) no one makes a big deal about it. And that's in DC which has some of the most draconian weapons laws in the US.

However, I guess people don't feel threatened when a guy in a wheelchair rolls up with a sgian dubh in his sock.
