Copper loose ring snaffle with lozenge. Softer than single jointed snaffle as it reduces pressure on the tongue and bars of the mouth as well as palate. Elliptical lozenge encourages a softer contact through salivation. Copper also warms up quicker than stainless steel for horses that dislike the cold feel of stainless steel. Can be used in most disciplines.
Snaffles consists of a bit mouthpiece with a ring on either side and acts with direct pressure. A bit is a snaffle because it creates direct pressure without leverage on the mouth. The snaffle bit works on several parts of the horse's mouth; the mouthpiece of the bit acts on the tongue and bars, the lips of the horse also feel pressure from both the mouthpiece and the rings. The rings also serve to act on the side of the mouth, and, depending on design, the sides of the jawbone.
The double jointed bit is one of the mildest mouthpieces, the two joints reduces the nutcracker effect which is found in single-jointed bits, and encourage relaxation in the horse. The bit applies pressure to the lips, tongue, and bars of the mouth.
Bits can also be made of copper, either the whole bit, or sometimes just the mouthpiece. Copper is felt to encourage salivation, which is thought to increase the sensitivity of the horse’s mouth. Because the metal is softer than stainless steel, copper bits wear more quickly although this is countered by mixing in small amounts of other metals. They can also corrode. Copper bits warm up more easily than stainless steel bits, this has to do with the conductivity of the metal. Some horses may dislike the taste of a copper mouthpiece.
