This bit is made from stainless steel. This alloy is best for bits because it extremely strong and resists salt and acids in saliva, and will never rust or spot.
The Kimberwick bit swivels at the bars, rather than relying on the center link to swivel, eliminating the possibility of pinching the tongue. Also it gives a more consistent and immediate signal to your horse, so his response time is reduced, with less pressure. If a horse is not new to the bit and is still gapping his mouth, excessive mouth movement or tossing his head, you will want to try a pinchless bit. Using a pinchless bit on a young horse will prevent inflicting pain, keeping the experience less stressful, resulting in easier and improved learning for the horse
