In the American style, also called the zig-zag method or fork switching, the knife is initially held in the right hand and the fork in the left. Holding food in place with the fork tines-down, a single bite-sized piece is cut with the knife. The knife is then set down on the plate, the fork transferred from the left hand to the right hand, and the food is brought to the mouth for consumption. The fork is then transferred back to the left hand and the knife is picked up with the right
Maybe I shouldn't be saying this since it's cultural, but I feel like if it is possible to use cutlery wrong, then I think the American style is definitely one of the wrong ways.
