When I started out all I had was the Norton 4/8 and I set many a bevel with that 4K and it worked fine. Looking back now that I have more hones and I have a Norton 1K I don't think I would start at the 4K again for true bevel setting. It took a lot of time on the 4K and I don't think I saw any advantages over the 1K at least on the razors I worked on.
