I have Spydies from every factory, except China and I have seen perfect symmetry and terrible symmetry from all of them! Probably the best is my Caly 3 CF, which has a fantastically thin primary grind and a faultless edge... the only blade I own that I looked at and decided immediately that it would never get reprofiled unless I damged it somehow. Hot on its heels are the S110V, CruWear, M390, 52100 and REX45 PM2s, all of which came with very good to near perfect symmetry, the only reason these have gotten reprofiled is to get rid of the last 1mm of unsharpened blade at the heel, it bugs me and now that I have a guided angle system it's easy to correct.
In general newer production knives have been better than older ones and the worst grind errors have been from Sakai, but that was on a knife from quite a few years back.
still more knives than sharpening stones...
