The 2 in 1 bit offers two impact levels by simply switching the sides of the bit. If you buckle the more angular side of the bit towards the horse's tongue, the pressure occurs more selectively. If you buckle the round side towards the horse's tongue, the pressure spreads over a larger area and it results in a softer impact. This stainless steel bit can be used with the reins set either on the middle or lower ring (which then provides more leverage).
