I had the most awesome shave I have ever had today. I have a neighbor who DE shaves too and we were talking and he said after I hot towel, hot lather etc, actually shave with cold water. So I did. Closest shave I think I have ever had. This may be old news to most of you but wow does it make a HUGE difference, at least with me it did. He is an engineer and was talking to me about the tempered steel blades and heat. I had been rinsing the razor with hot water in between passes but cold from now on.
