I sharpened my sr using a king 1000/6000 to set the bevel and a 12000 Chinese stone, finished with 1u film with wet paper underneath film. This sr pop hair off arm and was really sharp. First shave with it cut beard really well but when the razor came to my chin it seemed to drag and almost stop. I continued and I knew the razor was sharper then usual and it finally let go and big gusher on front of chin. I don't know if it was a mental thing or maybe the razor was too sharp and dug into the skin. I know what you are thinking, had razor at wrong angle coming down the chin, but the razor was at proper angle. Lather was wet with proper pre shave prep. Any thoughts?
