I don't know a Rockwell from a water well, but I know that I can put a good, sharp edge on my old Bear heads and that they have killed every animal I have shot with them. I'll keep using them untill I can't get them any more. I typically do use the bleeder blades, but I wouldn't have any trouble not using them. Mainly, it helps me match the weight just right, but I dunno how much they help or hinder cutting. On these Arkansas deer, I haven't had an arrow fail to pass all the way through yet. Several critters. I've not tried any large large game such as bear or moose or anything like that, but they are fine for here.
