I've been shaving with a Muhle R89, and at first I had to get used to the angle and pressure. It took me a few tries to begin getting a comfortable shave. As I'm traveling, I'm now using a Parker Travel DE, and the first time I used it I definitely had the wrong angle and pressure. Different razor, different technique. I noticed that the angle I was using was wrong as this razor is more aggressive. Therefore needed to adjust it. Razor burn is an inevitable part of the learning process. Light touch and small strokes held a lot.
