I have been shaveing with a Merkur 34c with feather blades. I occasionally use a Feather SS with Feather Professional Super blades for line ups and when I have time. I am currently looking for another DE razor. I am leaning towards a Rockwell 6s or a Muhl R41. I would say I don't have very sensitive skin, but I do have very coarse hair. What would you all recommend?
