This type of equine mouthpiece combines a specific cheekpiece design with a particular configuration of links or joints in the mouth. The cheekpiece offers lateral control and helps prevent the horse from turning its head too far to one side, while the linked or jointed structure provides multiple points of contact in the horse’s mouth. An example would be a metal mouthpiece with circular loops at each end extending upward toward the bridle, coupled with a series of ball-shaped links forming the central portion that the horse engages with its tongue and bars.
The design is favored by some riders for its potential to encourage a softer, more responsive connection. The multiple joints are thought to discourage leaning and promote lightness in the hand. Historically, such mouthpieces have been used in disciplines where precise control and subtle communication are valued, as it can be useful for retraining horses that lean on the bit.
