The snaffle bit encourages the horse to raise its head. It is often used on horses that walk behind the bit. When taking the reins, the mouthpiece slides up and the horse gets pressure in the corners of the mouth and at the back of the neck. The bit can be used with one or two reins or with pelham straps.
The single-jointed bit has one hinge point, which puts less pressure on the tongue than with a double-jointed mouthpiece. A single jointed mouthpiece mainly acts on the layers, the side of the tongue and can also act on the palate.
Sweet Iron develops through contact with (air) moisture and surface rust that tastes sweet and stimulates the horse's saliva production in a natural way.
