Factory Edge? I like better than factory edge, but then I don't mind the time that japanese water stones require. There are several ways, the one I mentioned above, there are flapper wheels that mount in die grinders that are great for starting edges, or cleaning them up, then hit with a finer stone to hone that edge. Arkansas hard stones arn't bad, many use jewelers rudge on cloth wheels, and a great one that I have seen a profesional knife sharpener use is a leather belt mounted on his own set up that involved the use of three wheel type of pulleys with a small amount of jewelers rudge (spelling?) applied. It put on a great razor edge that seems to last, without having to polish the entire edge as cloth wheels seem to.
