Snaffle bits are more gentle in comparison with other types of bits. However, they still provide sufficient control and communication between the rider and the horse. Snaffle bits can be used with horses that are sensitive to pressure or those that tend to bite. The shape of the bit helps to direct the horse's head and mouth in the correct direction. Snaffle bits are often used in conjunction with a curb bit, in a system called "bit and bridle." This system uses the snaffle to direct the horse's head and mouth in the correct direction, and the curb to direct the horse's head and mouth in the correct direction, as well as to apply pressure.
