Trust Sweet Iron Pelham Waterford
The Pelham is a cheekpiece with combined leverage on the poll, just behind the ears, and the chin. It can be used with one or two reins, but if you choose to ride with one rein, this must be done with a connection between the big and the lower loose ring. The strap used for this is called a Pelham strap. The greater the leverage effect, the bigger the impact. This bit comes with a curb chain, which should be well-fitted.
The Waterford mouthpiece consists of a series of elliptically shaped links. This mouthpiece is usually used with horses that are heavy in the hand and have difficulty relaxing the jaw.
