The Eggbutt Snaffle is one of the most widely used snaffle bits. The name comes from somewhat egg-shaped connection between the mouthpiece and bit rings. The chance of the lip being pinched between the mouthpiece and bit ring is less than most other snaffles. The mouthpiece itself widens at the sides creating more distance between the joint & horse's lips. The Eggbutt has a more fixed mouthpiece, meaning it does not move as much in the horse's mouth as a ring bit would.
