I carry a CRKT M16-13Z and have for about a year. I find it handsome and think that the safety is clever.
I've gone through several knives over the years, none of them particularly interesting as I am not much of a knife guy. If it's 3 inches long, partially serrated, has a quick deployment, and is decently made, I'm content.
Almost always a Buck of some sort. Used to be a 55 generally but the last year or so has been the new Spitfire cuz I like the pocket clip. Bucks are just great knives period but also if I break or lose the darn thing it's a fairly cheap replacement. If I lost my ZTs I'd be bent.
