The eggbutt is a common multi-discipline style of cheek piece for snaffle bits. It minimizes rings that pinch the edges of the horse’s mouth and provides lateral stabilization. By flaring out the ends of the mouthpiece and joining the rings with swivel joints where the lips make contact at the edge of the bit, the eggbutt can be a more comfortable for many horses. The edges of the mouthpiece are less likely to pinch the horse’s lips and because the cheek is fixed in relation to the mouthpiece, the bit offers moderate lateral control.
