JP Korsteel offers the unique JP Curved Design. This unique design features curved bars that prevent the bit from hitting the roof of the horse's mouth and eliminate the nutcracker-like action that can pinch a horse's tongue. A bradoon features smaller rings than a stand-alone snaffle. Features loose rings which help if your horse braces against the bit to evade the rider's rein aids and sweet iron which is a combination of iron and copper. The rust that forms over time is believed to encourage salivation resulting in relaxation of the horse's jaw.
