This double jointed three ring gag is made of solid stainless steel combined with a layer of sweet iron on the mouthpiece (blue). The mouthpiece features a lozenge, which activates the tongue and stimulates saliva production. As a result, the horse will be more willing to accept the bit. Salivation is even more encouraged by the coating of sweet iron on the mouthpiece. When this material reacts with moisture, warmth and air in a process called oxidation, the surface rust tastes sweet. The bit applies normal pressure on the mouth and is suitable for hard-mouthed horses. Mouthpiece thickness 13 mm, ring size 65 mm.
