The Sweet Iron bits are made of iron and have the well-known blue colour, obtained by heating during production. When in contact with (humid) air, Sweet Iron develops a rusty surface that tastes sweet and naturally stimulates the horse’s saliva production. This causes the horse to foam more, which in turn improves the acceptance of the bit. This rusting process (oxidation) changes the blue colour of the TRUST bits into silver or brown-grey, a desired effect of the Sweet Iron bits. When temporarily not using a Sweet Iron bit, an orange-brown layer of rust may appear on the mouthpiece. This can easily be removed by wiping the bit with a damp cloth. The orange-brown rusty layer is not harmful. Sweet Iron bits are suitable for all horses and help the horse to foam more, resulting in a better acceptance of the bit. The Sweet Iron collection offers the widest variety of mouthpieces, each with its specific purpose.
The Hackamore Combi short cheekpiece is a combination of a Hackamore with a bit. The Hackamore Combi distributes the pressure over the mouth and nose. The greater the leverage effect, the bigger the impact. The TRUST Hackamore combinations all have an adjustable screw above the mouthpiece. The lower the screw, the more pressure on the nose. This combination with short shanks has less impact than the long Hackamore Combi. The curb strap should be properly adjusted (not loose, not too tight but just right), so that the nosepiece is well-fitted and stays in place. The cheekpiece is attached to the rectangular part.
The Locked mouthpiece is single-jointed, but locks when it is hinged. So when there is counter-pressure, it works like an unjointed mouthpiece. This makes the effect stronger. The bit changes back into a single-joint mouthpiece when there is less counter-pressure on the reins. This makes it an ideal corrective mouthpiece for horses that, for example, push against the hand and/or walk through the hand.
