I know exactly how you feel. All I can say is, "It's not as hard to use your other hand as you may think."

The bottom line though is: "Do what's most COMFORTABLE for you." Are you comfortable only using one hand? Then don't change. Remember, there isn't a "right" or "wrong" way to shave. Everyone is different, and everyone has different ways to shave the hair that grows at different angles from you or me.

So if you can comfortably get all your angles with one hand, then no sense in complicating things by trying to switch! But for me, as a beginner, I found that some areas were tough to get with one hand, and using my left hand was not only EASIER (angle-wise), but also not as hard as I imagined.
