I suspect you might get a bias polling this group. I carry one wherever I'm legal doing so. I started out with Swiss Army back in elementary days and would ritually rotate it out of my pocket every Sunday night since I fall into that "no weapons in school" age group (not even cap guns, I checked in kindergarten). Through the years I've gone from CRKT and Emerson folders to Leatherman and Swiss Army with a Mercator and now Civivi scattered in there depending on where I'm spending my time and what I'm doing.
