Leverage bits are designed to apply pressure to the horse's mouth and poll through the use of leverage. The bit works by applying pressure on the horse's mouth and chin as well as on the poll. Leverage bits come in different variations such as Pelhams, Curb bits, and Gag bits. They have a shank that varies in length, and as the reins are pulled, the bit's action increases, creating more pressure on the horse's mouth.
