I used the black beauty I bought new back in 1970 (first time in several months). I put a Personna Red blade in it. I don't know why I don't use this razor more often. Close comfortable shave.... No wonder I was satisfied with this razor for more than 40 years and never looked for anything else....
Merkur Futur (3) with a Merkur blade (2). Yes a Merkur blade - I am re-evaluating now that my skills have improved after over a year DE shaving.
The Merkur is not the disaster of a blade I remember - not surprisingly my technique was the problem. I find the Merkur medium sharp and a bit harsh, but it gets the job done. 3 pass DFS - almost a BBS. No nicks, cuts, or blood of any kind. Very little sting with the aftershave. It's not as sharp as a Feather or a Bolzano and not as comfortable as smoother blades like the Astra SP and the Lord Plat.
