This final cheek in the Tool Box is designed for the finished, well-broke performance horse or tough mouthed older horses where the rider needs more control. It can be used as a schooling bit to get a horse to collect and break at the poll that is not responding to milder bits. It is also commonly used in competition in all disciplines, but should not be used all of the time for practice or daily training. The purchase is 2-1/2" and the shank 5-1/2". The calvary 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 of the mouth and chin.
