Right handed writer, but I do lots of other things with both hands without noticing; say, if I pick up my toothbrush with my left I'll brush with that hand, and vice versa. When shaving, I'll switch hands to do respective left and right.
I'm right handed, but was able to use both during my first shave. I just can't write with my left. People already have trouble deciphering what I write with my right hand.
Shave righty but with a backhand. Can shave lefty. Play pool right and left equally. Shoot right with a touch of left when needed. But went to catholic school and had my left hand smacked for trying to use it, so was probably a lefty and just learned righty.

M.I.B "Then why are you smiling?"
I.M. "Because I know something you don't know."
M.I.B. "And what is that?"
I.M. I...am not left-handed!"
I am predominately left handed but I can teach myself fairly easily to do most things with my right hand. I have no problem shaving with both right and left hand.
I know this thread has been dormant for a couple years, but I was just directed here from a left handed thread at The Nib and had to reply. I'm mostly left handed. The only shaving I do with my right is ATG on the right side of my face. I say mostly left handed because I write, throw, and bat left handed, but play golf and hockey right handed.
