While I don't always have this *on* me, it's always in my Jeep, so always *with* me - plus it's a Becker.
The folder I carry the *most* earns that title because I've had it since it was new, in like '82 or so. I lost it once. Gone for a couple of years. Packin' up to move from LA to Bama, picked up the easy chair that had been sitting in the same place for two or three years, and this little gem fell out. I'd say it "came home" to me, but it never left home!

As far as "normal sized" folders, I've had this Bradley Alias I for about 2 years now I guess, and it sees the vast majority of pocket-time over all my other larger folders. Love it. "The poor-man's Sebenza" is what it has been called before. Never had a Sebbie, but if they're as similar as people say they are, I probably never will, as there's no reason to spend the extra $125 or so bucks on a Sebbie as long as I have this:
I've got a bunch of other folders, but the only other one that's seen more than an occasional session in the pocket besides the Alias, is this Kershaw Breakout. Bought it on a whim. I like the 14C28N steel a lot better than Kershaw's previous mid-grade steel, the 8CR13MOV. Much better rust resistence, holds its edge much better, and having never owned an auto-opener before, this was an inexpensive way to see if I liked 'em or not at less than $70 bucks. Turns out I do like this one, but not enough to go buy a Protech or Piranha for at least twice as much. Cool knife though, just not cool enough to knock the Alias out of my pocket very often.
