The TRUST Curbgag Blue SI Waterford is similar to a pick-up run, but has a slightly different effect. The pressure will not be mainly on the poll, but rather the lower jaw & chin. The cord runs under the chin and the braking pieces are attached to the extra ring at the top. This bit is effective for strong, hot horses and is mainly used by showjumpers. This bit is not suitable for inexperienced riders.

A Waterford mouthpiece consists of a series of rounded links. It is a flexible bit that forms towards the horse’s mouth and creates an even pressure. It can move in all directions, making it difficult for the horse to grip the bit so that the rider retains proper control. This bit is not suitable for inexperienced riders. In soft hands this mouthpiece is friendly but with a hard hand the bit can be sharp.

The Sweet Iron bits are made of steel and have a recognizable blue color. Sweet Iron develops surface rust through contact with (air) humidity that tastes sweet and naturally stimulates the saliva production of the horse. This will cause the horse to foam more, which ensures better acceptance of the bit. This rusting process (oxidation) changes the blue color of the TRUST bits to brownish-gray.
