cheesecutter noun a wedge-shaped hat UK From the shape, and the memory of the vaguely similar late C19/early C20 “cheese-cutter caps.”
There was a short spell when tearaways wore the “cheesecutter,” a cap narrow at the peak and perched forward on the head–very much in the style of Del-boy. — Brian McDonald, ElephantBoys, p. 229, 2000
