it has edges. Generally more common in western riding. Has similar action as the loose-ring, though is a little more stable in the horse's mouth and the rings may be less likely to pinch. Tubular Butt: Similar to the eggbutt but with a sliding loose-ring and is suitable for use with reins that are connected with various knots. Wing Cheek: A relatively recent innovation in snaffle cheeks, the wing bit offers extensive protection at the corners of the horse's mouth by having winged plates on the ends of the mouthpiece that curve around the side of the mouth. Essentially acting like a bit guard, these metal plates ensure that the rings of the bit do not rub or pinch against the sides of the horse's mouth.
