Adjustable horse bit
摘要:
An adjustable horse bit that acts as a snaffle bit (direct-pressure) under normal circumstances and transforms into an elevator bit (leverage bit) when a threshold force is applied to a hingedly attached lever section of the horse bit cheek piece. Absent the threshold force, the lever section retracts to transform the elevator bit back to a snaffle bit.
