The only knife I've ever been able to whittle hair with out of the box was, oddly enough, an Esee 5. I've bought Benchmades, Spydercos, Cold Steels, Bucks, Kershaws, ZTs, etc. Nothing was ever that sharp.
I would say Spyderco and Cold Steel, but CS looses it's edge as soon as you cut a piece of paper with it, and you will never get that edge back.
Buck knives.
I would have to say Kershaw but for the price they cost I was very surprised at how sharp Rough Riders come!
