I think the biggest mistake folks make is to try the left hand right away and then become disappointed at the early results. The most important thing is to start off just holding the razor in the left hand and getting use to it being there. Practice the strokes and changing hands and all the movement you can before ever putting the razor to your face. When you do, then just try one little area until you get used to it and build from there just like when you learn with the dominant hand. If you take a little extra time, it can definitely be learned and it is unreal all the things that you can start doing with the opposite hand then.
Hey Bruce, come on down and help me. There is never a lack of razors to hone in this house.........:rock:
Have fun
