there is perhaps some truth in this. *most* people are not used to sharp knives.
gave my father-in-law a swiss army knife for christmas. he recently remarked to me how really useful it has been but that he had nicked himself a couple of times because he isnt used to that sharp of a knife. it was right out of the blister pack; i didnt do anything to the edge at all. he isnt a doofus, he was a biology teacher and likes fishing and cooking so he has handled a knife before.
Wouldn't be too surprise if some manufacturers skimp on the sharpening as it seems a lot of people aren't use to a sharp knife and can get away with it. I just handed a friend my Cryo a few days ago to look at, 1min latter I hear a "Oww thats sharp" and hands the knife back to me.
