Buck Vantage
Hi, my name is Arfin, and I'll be your Buck Knives fanboi this evening.

Have a look at the Buck Vantage (the large one). Available in three configurations, the Select, Avid, and Pro, it will fit pretty much any wallet.
The Select is done in 420HC steel, with handles of FRN or PaperStone. I have both kinds, and actually prefer FRN, even though the PaperStone is lighter and more grippy.
The Avid is done in Sandvik 13c26 steel, with handles of Dymondwood, which is a satisfyingly warm and smooth material which won't tear up your trousers.
The Pro is done in S30V steel (really hard stuff), with handles of G-10, which is really grippy, but which is also hard on fabric unless you coat the surface on the clip side with something like nail polish to smooth it out a little.
I have the Select in FRN & PaperStone, as well as the Avid. I prefer the Avid, as the steel is one that I'm familiar with and I know exactly what I can expect from it, and the handle is easy on my clothes.
Now, if you suddenly have an attack of the
I-don't-care-what-it-costs, I can also recommend the Buck Paradigm. The Paradigm is basically an assisted open version of the Vantage. It's the same size, and the blades are essentially the same. Thing is, now you're looking at $100 for the Avid version (the one I have), so this might price it out of your selection. Excellent knife, though. Very "energetic" when it opens, so I will often use my other hand to ease it open when I'm around other folks. No need to alarm people.

Oh, as long as we're mentioning assisted openers, you might also have a look at the Kershaw Packrat. Splendid knife with a well designed handle and a blade shape that's good for all kinds of stuff.
Also done in Sandvik steel (14c28n), and available in orange or black.
Mine is orange. I like it a lot.
All of the above mentioned knives are in my EDC (everyday carry) rotation.
Hope this is of some use to you.
