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. The wings prevent the bit from being pulled through the horse's mouth, help with steering and apply lip pressure when the reins are used. This is a very popular all-round bit. Features loose rings and made from stainless steel which does not flake or rust and is extremely durable.
