Trust curb gag with a double jointed mouthpiece, with sweet iron.
A curb gag is similar to a snaffle bit but has a different effect. The pressure is now not placed behind the ears but on the lower jaw / chin. The cord runs under the chin and the cheek pieces are attached to the extra ring at the top. This bit is effective for strong, hot horses and is mainly used by show jumpers.
The double-jointed bit has two hinge points, is shaped more towards the mouth and lies a bit looser in the mouth. This bit acts on the tongue, the layers and the corners of the mouth. Be careful with narrow lower jaws, the hinge points can then press on the layers, which can cause wounds. Compared to a single jointed bit, this bit acts more on the tongue.
Sweet Iron develops surface rust through contact with (air) moisture that tastes sweet and stimulates the horse's saliva production in a natural way.
