- As the name implies, the side pieces of a D-snaffle have the shape of a D and therefore cannot be easily pulled through the mouth.
- Because of this D shape, more pressure is obtained on the horse's cheeks, which makes maneuverability easier.
- This makes the D-snaffle a nice bit for teaching young horses.
- Depending on the type, thickness and material, a D-bit gets a sharper or softer effect.
- 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.
