I'm left-handed and have permanent nerve damage from a neck injury. My right arm and hand muscles and sensation are either shot or compromised and a slight hand tremor comes and goes. If I can learn to shave with both hands, anyone who wants to will learn. Starting out with a plastic knife (I recommend the Bojangles knife cause I like their chicken) it felt natural using my non-dominant hand in less than 10-days.

It works either way for me now. I can shave both hands, lefty and righty.
