I use which every part of the blade reaches the area to shave best. I shave w/ just my right hand so I make use of the tool at hand to the best of it's abilities. For example, left side gets the toe on the sideburns and the right side gets the heel. The toe is used to style my mustache, all parts of the blade on my chin, middle on my cheeks and parts of my neck as well as the toe and heel on my neck depending on the neck contour and angle of attach I can maneuver. At times you may think I am using the Zamboni approach but I like to think I am putting some thought into my shave. CarrieM tests all of my edges when I finish honing them. It makes here very nervous to watch me shave my chin and other tough spots. Maybe she thinks I will be putting some body parts on the sink.
