Korsteel Stainless Steel Jointed Slotted Ring KImblewick BitWe love the JP Korsteel Stainless Steel Jointed because it combines the action of a snaffle and curb into one bit through one rein. The curved mouthpiece eliminates the nutcracker action of the joint hitting the roof of the mouth and the tongue being pinched. This bit is for experienced hands. Curved bit to reduce the "nutcracker" action and to alleviate pressure on the tongue and bars of the mouth. Prevents contact with the roof of the horse's mouth.
