Where to start with so many available bits? As overwhelming as choosing a bit can be, it is an important part of the tack that deserves more attention than it generally gets. When a bit does not fit right, the horse may show difficulties in using its body properly or show other signs of discomfort. Considering every horse has its own unique anatomy and preferences, it is impossible to offer a ‘quick-fix’ suitable for every horse. Since it might take some experimenting to find the right bit, consulting an expert on bits can make choosing easier.

Less space

Two of the basic things to consider when choosing a bit are the length and thickness. The easiest method to determine the needed length is to try different sizes of bits. A bit that is too small will pinch, if it is too large it will slide back and forth. If the bit fits correctly, you should be able to place a small finger between the mouth and rings on each side. Finding the right size is easier than deciding on the required thickness of the bit.

It is a common belief that a thicker bit is softer and friendlier. The theory supports the belief: more surface means more distribution of pressure and thus a milder effect on the mouth. In practice, modern horses are bred for elegance and as a result have less space available for a bit. In this case a thick bit is neither friendly nor soft: it does not fit. The choice for a certain thickness should be made based on the anatomy of the mouth. The bit should be comfortable and the horse should be able to properly close its mouth.

 The Mouthpiece

The mouthpiece is the part of the bit that rests in the mouth of the horse, it partly determines the effect a bit has on the mouth. There are roughly three common types of mouthpieces but in combination with the rings many variations of bits exist.

Sweet Iron bits are known for the sweet taste of the mouth piece. Besides, the bits are anatomically shaped and available in many shapes and sizes.

This mullen mouth eggbutt snaffle is made of solid stainless steel rings and a mouthpiece of mild steel combined with a layer of sweet iron on the mouthpiece (blue). The sweet iron stimulates the chewing process and saliva formation. When this material reacts with moisture, warmth and air in a process called oxidation, the surface rust tastes sweet. As a result, the horse will be more willing to accept the bit. The blue colour disappears eventually, but the taste of the surface rust remains.

The anatomical design of the bit follows the shape of the horse’s mouth, which allows for a gentle and even pressure distribution. The mullen mouthpiece provides stability and puts more pressure on the mouth than a single or double jointed loose ring snaffle. Mouthpiece thickness 14 mm, ring size 65 mm.

The eggbutt snaffle has fixed cheek pieces. Aids have a more direct effect and the bit allows less freedom of movement compared to the loose ring snaffle, making it better suited for horses that tend to play with the bit too much.
