Harvey bends the wing sharply away from the breast. Using a heavier, stiffer 6-inch blade, he cuts first through the muscle where breast meets wing, then through the joint. Note that there is no cutting of bone here—just a separation, using the edge of the blade, between the ball at the base of the first wing bone, and its socket by the breast. (Note that he sometimes removes the pinion as well—it's just bone, tendon, and skin—and reserves it for the stockpot.)
