The full cheek snaffle has narrow arms which project above and below the rings, preventing the mouthpiece from sliding in the horses mouth and to emphasize the tuning aid. This is a great all purpose training snaffle with just the right amount of weight to keep a steady contact. The single joint applies a nut cracker action which applies pressure to the tongue, the bars of the mouth and the horse's palate. * The full cheek snaffle has narrow arms which project above and below the rings, preventing the mouthpiece from sliding in the horses mouth and to emphasize the tuning aid. * This is a great all purpose training snaffle with just the right amount of weight to keep a steady contact * The single joint applies a nut cracker action which applies pressure to the tongue, the bars of the mouth and the horse's palate.
