This final cheek in the Tool Box is designed for the finished performance horse or tough-mouthed older horses where more control is needed. It can be used as a schooling bit to get a horse that is not responding to milder bits to collect and break at the poll. It is also often used in competition, and should not be used for daily training. The purchase is 2-1/2 and the shank 5-1/2. The Cavalry designed shank is angled back to the horse, but at a straighter angle than the 7-1/2 model, causing a quicker, more immediate response. The purchase/shank alignment ratio increases leverage, creating greater realized pressure to all points of contact. The 1″ x 1-3/4″ Correction is a step up in leverage and control. Applies increased pressure to all parts of the mouth and to the sides of the tongue. Not typically used in training, but often used to school horses that need a firmer reminder. Works well as a stopping or collection tool.
