I had an ex-boyfriend who could never seem to grasp the idea that you hold with the fork and cut with the knife, regardless of which hands he was holding them in. As he is left-handed, I tried to get him to use the more European method of not switching, thinking that might help, but to no avail.... Still to this day, if you watch him eat, he sort of stabs the food with the knife and then tries to tear off bits with the fork.
Maybe this is some sort of food utensil dyslexia???
My mother inherited the set of real European silverware from my father's side of the family. The backs of the forks are all as elaborate as the fronts, as you see that view when you maintain the fork in your left hand for cutting and eating. It's really quite lovely. Personally, I think the convention of switching utensils for cutting and eating is a personal choice, as it's not like you can't eat if you don't switch the silverware from one hand to the other.
