Sweet iron will rust when it comes into contact with (air) humidity; the surface rust tastes sweet and naturally stimulates the saliva production. This will cause the horse to salivate more which in turn encourages better acceptance of the bit. The rusting process (oxidation) changes the blue colour of the TRUST-bit to a brownish-grey.
An elliptical (double-jointed) mouthpiece has two hinges, is shaped more towards the mouth and lies somewhat looser in the mouth. This bit exerts pressure on the tongue, the layers and the corners of the mouth. Be careful with narrow lower jaws, the hinge points can press on the layers which can cause wounds. Compared to a single jointed bit, this bit exerts more pressure on the tongue.
A TRUST-bit is completely handmade. every component is welded together and polished by hand. By briefly heating the sweet iron it receives its beautiful deep blue colour. The finishing touch: stamping on the size and brand name.
TRUST bits are unique and guarantee the highest quality control standards.
