As with the Pelham, the action of the Kimblewick is dependent upon the position of the rider's hands. The rein slides on the Dee shaped bit ring.
If the hands are lowered prior to pressure being applied to the reins, the rein will slide about an inch and the bit will assume roughly a 45° angle in the mouth. Causing the mouthpiece to act in a downward and backward motion on the lower jaw, this is complemented by downward pressure on the poll, giving the bit a lowering action.
It is supplied with nylon backstrap.
The Bomber Blue is a unique bit which produces amazing results for the majority of horses. The mouthpiece is ported to give tongue relief. The material used allows the bit to remain light and it encourages salivation. It is particularly well suited to horses that object to metal mouthpieces.
