I carry a leatherman c33Lx. It's not the size of the knife that attracts attention but the why I open it. I work security in a hospital and use it on a regular basis. When I open it slow and discreetly no one notices or no one cares but when I open it fast with the flick of my wrist so it makes a snap noise when it opens, man oh man, the looks I get and the comments. "Why do you carry a knife like that? Is that legal?" But after I show them how I open it they calm down.
