I usually shave with a Muhle R-41, which gives me a BBS that lasts for 12-14 hours. I can also get a BBS shave with other razors, but it typically lasts less (with my Merkur Progress it lasts only 8-10 hours). I am now thinking of buying a Feather AS-DS. I understand it has an angle that, once mastered, can give a BBS shave. But is this a lasting BBS? For the sake of marital life, I'd rather not have stubble on my face when I come back from work!
