Baucher The baucher has an eggbutt-like ring at the mouthpiece for the rein, with an upper cheek that has a ring at its end, to which the cheekpieces of the bridle are attached. The mouthpiece does not slide on its ring (which would have put the bit in the gag bit category instead of the snaffle). This bit lies flat against the horse's face, and is quite fixed in the mouth and concentrates pressure on the bars. However, contrary to common belief, this bit does not create poll pressure.
