I rotate my carry pretty regularly, but I've got a couple that always pop up. A Victorinox Explorer with Stay Glow scales is always in my work bag, I've got a green alox Cadet that's been put through some pretty tough work, and a Rough Rider copperhead that's used when I need a knife, but I know it could get pretty nasty, lost or damaged, like working under the house on a water leak or something.
