The 6” cheek has a 2 1/2” purchase and a 3 1/2” shank. This ratio (the difference in the length of the purchase and shank) and the swept back design of the shank make this a mild cheek. A slight step up from the snaffle. The 5 1/8" mouthpiece is inlaid with copper to stimulate salivation, 3/8” in diameter, and curved for soft, evenly distributed pressure. Applies pressure to the chin, bars, and corners of the mouth. Gives added pressure to the tongue for more feel.
