I'll agree with the ones that keep popping up: Native, Buck 110, Endura/Delica, Kershaw Onions, Ka-Bar Dozier folders, Byrd G-10 or stainless handles, Tenacious, All for the Under $50 crowd.
If you step up, then Kershaw starts taking over. Fancy leeks, sprint-run Titanium folders, ZT line, almost anything they make.
Yes, Benchmade still has their hand in it (710, 42, 94X), as well as Spyderco (Military, Chinook, ATR), but Kershaw is quickly becoming my favorite with the Junkyard Dog II in SG2, Tyrade, Composite bladed anything, ZDP-Leek, mini-Cyclone, etc.
