Trust Sweet Iron 2½ Ring Single Jointed.

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.

2½ & 3 Ring Bit:

A 2½ & 3 Ring Snaffle is also called a Pessoa bit and can be recognized by the extra rings on top and at the bottom of the regular bit rings.
The top ring is used to attach the cheekpiece and the bottom ring the rein.
When using the rein, the top ring will tilt forward and create leverage.
The strength of the impact is determined by the type of mouthpiece, material and number of rings.
A 2½ ring snaffle is therefore less effective than a 3 ring snaffle.

Single Jointed

A single jointed bit has a hinge point in the middle that puts pressure on the lips, layers and sides of the tongue. A single jointed bit squeezes the tongue slightly under pressure and puts less pressure on the tongue.
A single jointed bit rises slightly in the middle and can sting the palate. In this case is it better to choose a double-jointed or straight mouthpiece.
A single jointed bit is a good basic bit, suitable for many horses and riders.
