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. Features a French link jointed mouthpiece which has a small, flat plate between the two bars of the mouthpiece. The plate causes less of a nutcracker like action on the tongue and is milder than a single-jointed bit, oval-shaped fixed eggbutt rings and made from stainless steel which does not flake or rust and is extremely durable.
