I have seen so many cooks and articles where it shows cutting a large chicken breast in half crosswise. I don't have a word for this -- maybe "breast butcher". When I was a kid my mother did fried chicken ALOT and she always cut out the pulley bone which was a nice side which left two small pieces of breast to fry. My sister and I always fought over the pulley bone. I would never consider cutting a breast crosswise. It makes both pieces look like thighs. I like a breast to look like a breast.
