To keep it semi-local for you, check out the Blade-Tech Wegner Pro Hunter from the fine folks in Tacoma. Mine is S30V steel, plain edge blade, G-10 scales, flat saber ground, easy-open ambidextrous hole

, and so flat it carries unnoticed in the pocket until I need it. While it ain't cheap ($125'ish online price), I've found quality tools are worth the extra cash outlay up front for the aggravation they save me later in not having to jury-rig around the shortcomings of the tool while in use. The folder in the pic below is my Pro-Hunter when it looked a lot better than it does now.
(My recommendation is to get the real one, not the 440C Lite series. However, if budget restrictions apply, folks who have the Lite series say they are very nice knives.).
As the name implies, its design was motivated to be a pocket folding hunter, which deer hunters report it does a fine job of. The shape is deceptive.... the long-bellied drop point (but still somehow looks upswept) blade & hump-backed handle, with all those Persian-looking curves, make it look like some kind of porpoising alien medical device that won't fit well in the human hand. WRONG!!! I find it's super comfortable and friends who are into martial arts say it's a more than ample self defense blade in all sorts of grip positions.
I've used the hell out of mine. It's always in my pocket and is my default go-to tool (note I said tool, not just knife). So it has seen a lot of use scraping, prying, gouging, performing hack 'n slash on packaging, and doing things Tim Wegner would likely flog me for doing to his knife. I figure that if I'm not good in this life, in my next life I'll get reincarnated as my own pocket knife.
The only downside I've found to the Wegner Pro-Hunter is that the jimping notches on the front of the hole-hump chews at my pocket when re-pocketing the knife. But I must say that the jimping there and elsewhere along the blade and in the choil area, make this a *super-secure* knife in hand. Also, the fact that it's a liner-lock may make it awkward for lefties, as you noted.
Some specs from the
Blade-Tech webpage for the Pro-Hunter model:
Blade Steel 1/8" CPM-S30V (Flat Ground)

Bottom Line: I like it so much that if I lost it, I'd replace it immediately with the same model.
