How sharp a knife is depends on it's design and intended use. For example My DFCG was not hair popping sharp however it was designed as a an all purpose chopper. My GB axe was hair popping sharp out of the box however, it's intended purpose is to chop softer green wood not dry hard wood.

For quite awhile Chilled Metal blades were arguably the most consistently sharp knives out of the box. I've yet see one that wasn't hair popping sharp out of the wrapper. But that's always been one of there main selling points.

Spyderco and Benchmade at least to me have always consistently delivered very sharp knives. Personally edge sharpness is not a big deal to me as I generally re-profile or sharpen it anyway.
