I've been shaving with my Weber non-DLC razor and Voshkod blades for a few years now and always had trouble shaving my upper lip and my chin/neck area ATG. If I'm not careful I would get a few nicks, and finally would not get a BBS shave in those areas.
Just got a Rockwell 6S and shaved in the R3 setting, WOW! This razor is smooth. At first I wasn't even sure I was using the correct angle and actually cutting my whiskers. Then I could hear it cutting but would not feel a thing. Finally I was able to go ATG in my upper lip and neck area. Not a single nick this time.
Very nice solid construction. It will definitely outlive me. If I would have to pick just one razor, this would be it.
