This cheekpiece is a combination of a hackamore and a bit. The hackamore combination is a cheekpiece with leverage and gives pressure on the nose, chin and in the mouth. The longer the shanks of the hackamore the stronger the effect. This combination with short shanks has a milder effect than the hackamore combi long. The Sweet Iron bits are made of steel and have a recognizable blue color. 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 will encourage a better acceptance of the bit.
