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 eliminates the nutcracker-like action that can pinch a horse's tongue. Features an oval link mouthpiece which relieves some of the pressure on the tongue when the rein aids are applied. Because the link is rounded, this mouthpiece is considered slightly milder than a French link loose rings which help if your horse braces against the bit to evade the rider's rein aids. Made from stainless steel which does not flake or rust and is extremely durable.
