Korsteel Sweet Iron Loose Ring Snaffle. The Sweet Iron Loose Ring Snaffle is a single jointed bit with a nutcracker action that works on the tongue, the bars of the mouth and can have action on the horses palate. The Loose Ring Snaffle is ideal for horses with a tendency to lean on the rein; the loose rings of the bit provide more movement than a fixed cheek bit and allow the rider to move the bit more in the horses mouth preventing the horse from leaning and grabbing hold of the bit as easily. The Sweet Iron encourages the horse to salivate and accept the bit.
