I'm inclined to recommend the Vantage
Avid (Sandvik steel).
I find the Dymondwood handle is smooth enough that it doesn't tear up the fabric on trousers.
I have the Vantage Avid, Vantage Select (Paperstone), and Vantage Force.
The Avid is easiest on the pocket fabric. The Select w/Paperstone scales is a more "grippy" handle, but rougher. The Vantage Force is heavier, has a black coating that rubs off the blade, and the handle is aggressively rough.
If you don't anticipate needing to crawl around in the dark with a blade that won't reflect light, and if you don't think you'll be needing the slight ramp/bump on the back of the blade for thumb support, and if you won't be needing a handle that could conceivably stay grippy when wet, then it's possible the Vantage
Force is a little overkill for you.
If you spend most of your time in everyday environments, offices, stuff like that, then the Vantage
Avid is my top recommendation. I own and use the Vantage
Select as well, and I have no complaints about the 420HC steel blade, but I prefer the Sandvik myself.
I have no doubt that the Vantage
Pro is and excellent knife. I have only two reservations about it:
1) the handle (in G-10) is a bit rough for my tastes, but I do have G-10 handled knives and can attest that it's a good handle material,
2) I haven't been able to convince myself that the extra cost for S30V steel yields that much more useful quality than the Sandvik steel.
I'm therefore going to recommend on of the original Vantage models for your first one. Once the addiction takes hold you can grab one of the
Force models.
