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.
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.
