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. Loose rings are not fixed like dee-rings and eggbutts but can move freely through holes in the mouthpiece. Features loose rings which help if your horse braces against the bit to evade the rider rein aids. Made from stainless steel which does not flake or rust and is extremely durable.
