I bought a 551 Grip in 440C 8/03 local store and a 201 Activator+ in D2 from a mail order store 12/07. Neither would cut copy paper without roughly tearing it. I generally refer to this, in error, of course, as 'so dull it takes external heat to cut butter'. I had a Sharpmaker - and that 201 - then the 551 - became sharp users. Skip ahead...
Earlier this year, I started buying Benchmades... and they were all delivered sharp. Varying bevels from knife-knife - but copy paper slicers all - some were hair 'razors'. They include Skirmish, Rukus, and some Snody folders - all decent. The metal ranged from D2, 154CPM, S30V, to even M4. Hand sharpened, you can still get a less-than-perfect edge - just return it. With their 'LifeSharp' service, return a used one with $5 and it'll come back very sharp, at least according to my friends on the BM forum. From my experience, current production is pretty good! I've never had a functional fault with a BM, either.

PS Oddly, I've never found a new Buck, Kershaw, or Spyderco that didn't come as a razor!
