I love the Executive. There. I said it. I'm carrying a pansy little Swiss penknife with my wallet every day.
I've had a Pocket Pal for years, and when I was wearing suit pants all the time, it was perfect because it is big enough in blade and handle to do most things, but slim and light to not be a burden to light trousers.
When I joined the Army, I left all of my knives at home, and the first day at AIT, I went to the PX and bought a Tinker because it was the best pocket knife in the store. I still have that knife, and carried it all over the world. I really have a lot of good memories with that one, and still break it out to carry occaisionally. Carried it for a month last year all by itself. I actually like my Executive better -- because it is smaller and has a real nail file and scissors. I like the Executive better than my wife's Classic because it is more robust, and has that real nail file, too. It's the only knife I know that she'll usually have, because it's on her keys. She has a Wenger version of the Pocket Pal as well, Alox, and likes it because it's so skinny, you can't even see it or feel it in your pocket. That one gets carried a lot, but not as reliably as the Classic. My daughter even has a Classic, and prefers it to her lockback.
I bought a little Recruit for my emergency kit, and every time I pick it up I'm tempted to just carry it in my pocket instead of the main pocket knife I'm planning to carry that day. I like how smooth the back is compared to the Tinker, and again, it's a bit more compact than my old Tinker.
So, I haven't had a non-favorite among them, besides Classics. I know, I know, it's "enough" for many, even jackknife carries one, but... I just look at the microscopically skinny little blade and think "it's gonna break!" Other than those, every one I've bought has served me just fine. And the Classics serve the ladies I got them for as they want them to do.
