You think an exposed chin would be the easiest part of your face to shave clean and smooth. After two years of daily shaving with different razors, honed by different professional honers, my chin is the hardest and longest part of my face to shave clean and smooth. Sometime this is not accomplished. I do have a fairly heavy beard, but the chin should be a matter of just passing the razor and keep on going to other parts. I go across, sideways, down, up, front of the blade, middles of the blade, back of the blade, 30 degrees, 15 degrees, 5 degrees and any other way gravity allows. At the end of the shave, I tried my best and be happy with any result of the outcome of the shave. Do you have the same problem? Juan.
