This bit uses a lever action which raises the bit in the horses' mouth this helps the rider to maintain control of the horse. Poll pressure is also applied when the reins are placed on the lower ring. When using the Korsteel Dutch Gag two reins should be used. One on the main snaffle ring of the bit and the other on either of the two lower rings. If only one rein is to be used when using the Korsteel Dutch Gag then roundings should be used to help maintain a better contact with the horses mouth. The Korsteel Dutch Gag is made from stainless steel.
