This bit is made of stainless steel, which is guaranteed never to rust, bend or break.This gag bit is based on an eggbutt snaffle with the jointed mouthpiece having a nutcracker action. Pressure on the gag rein causes the bit to move higher in the horse’s mouth. This creates poll pressure and obviously quite strong pressure to all areas in the mouth. It works well on horses that are heavy on the forehand as well as most forward going horses. Ideally used with double reins, this bit can also be used with a single rein on the gag itself, or with gag reins.
