hokay, here are some suggestions:
(1) buck mayo TNT (the best EDC in the under $150 price range (aftermarket)) for urban use. Solid construction, Paul Bos heat-treated S30V, framelock, very nice design
(2) spyderco military, or, paramilitary (on my watchlist currently) S30V
(3) camillus dominator - ti frame, framelock, robo-assisted (or manual), S30V
(4) swamp rat folder (coming out soon) - 4 inch S30V
(5) William Hency Monarch/Kestrel - as long as you're not going to abuse your knife, this knife's fit and finish is above all others
(6) Wegner Pro-hunter G10
(7) Buck-Strider (if you're gonna use your knife as a pry bar)
