I've got 7 Benchmades, and haven't had a single problem with a one of them other than the best edge on them was still not as sharp as I wanted it. That's not a quality control problem, IMO, but more my problem, since about half of the Spydercos that I have bought (about 7 or 8 again) had edges less sharp than I like also.
Just another perspective.
OBTW, the lowest end Benchmade that I ever bought had the best edge that I have seen, other than Buck's Edge 2000.
