Trust Sweet Iron Loose Ring Waterford.

Sweet Iron

Sweet Iron bits are made of blue steel and release a sweet-tasting surface rust through contact with saliva, which stimulates the horse's saliva production in a natural way. This sweet surface rust will cause the horse to foam more and accept the bit better.
When a Sweet Iron bit is temporarily not used, an orange-brown rust layer can form on the mouthpiece. This can be easily removed by wiping the bit with a damp cloth.

Loose Ring

A loose ring snaffle is a basic bit with loose movable bit rings and is therefore quite loose in the mouth.
Depending on the type, thickness and material, a loose ring snaffle gets a sharper or softer effect.
It is important that the loose ring is not too narrow, otherwise a skin from the corners of the mouth can get in between.
If your horse does have problems with this, you can use rubber bit rings if necessary.
A loose ring snaffle is a good basic bit, suitable for many horses and riders.

Waterford

The waterford mouthpiece consists of a series of rounded links that flexibly conform to the horse's mouth, creating an even pressure distribution.
The Waterford mouthpiece is movable in all directions making it difficult for the horse to grasp the bit.
A Waterford mouthpiece is not suitable for inexperienced riders, with a soft hand this mouthpiece is friendly but with a hard hand the bit can be sharp.
