No, this isn't a challenge and I don't suggest anyone try it, although I'm sure most experienced straight shavers could mange. What I'm wondering as a beginner is how much the feel of the blade on your face plays in shaving for you? Right now it's all with my eyes, when I try to focus my mind on the blade position by the feel of it on my face it's only a vague notion. I can feel the cut being made to the whiskers through my face but that competes with the greater sensitivity of my fingers feeling it through the blade. Still, all positioning is done with the eyes first then fingers then facial sensation.
