The JP Korsteel Stainless Steel French Link Eggbutt Snaffle Bit is a double jointed bit that helps to evenly distribute pressure over the tongue. Combined with the uniquely curved mouthpiece this bit is designed to reduce the "nutcracker" effect as well as alleviating pressure on the bars of the horse's mouth. The eggbutt rings provide a more secure and consistent contact for effective communication between horse and rider.
