I'm trying to get a feel for what most think is proper way to straight razor shave with regard to using your left hand for the left side of your face and the right for the right side of your face?

I've been shaving fine with just my right, but the more and more I shave, the more and more I see that the devils in the details and a constant switching of angle against the face, angle to the horizontal, portion of the blade that touches your face (back, middle, tip of edge), and even a switching of which side of the blade you use is needed. Again the more I shave the more I see that this is best done if I was ambidextrous.

Also when I start shaving the right side of my face at the begining, my hand is blinding me and it be easier if I used my left hand. I basically have to have the blade perpendicular to the mirror so at least I have a side view of whats going on.

While I'm at it, talking about switching sides of the blade. On one side of my razor the bevel is like twice as wide as the other side is that normal? I know all that matters is the point or edge, but does the bevel depth matter?
