Kinda where I am. Right hand dominant, but weirdly, I cut food with my left and brush my teeth with my left. I'm also left eye dominant (my right eye totally sucks), so on the rare occasion that I shoot a long gun like a rifle or shotgun, I do that as a lefty as well.
Ditto on brushing teeth. I can eat with either hand, but usually eat with knife/fork with the left, and if only using a fork/spoon with the right, but can vary.
I play piano, and the right hand is definitely more dexterous there, but I think it's just because of the nature of how most piano pieces are written...
