Warm, sweet iron mouthpiece with a copper lozenge on the middle link. Quality made, nice a slender with smooth joints, unlike some of the clunkier, cheaper bits.
Sweet iron coating is warmer in the mouth, and becomes sweeter once it starts to oxidise.
Loop ring, gives a touch of poll pressure.
Very popular bit that encourages the horse to salivate.
Sweet iron bits are designed to oxidize, turning from black to a brownish-rust colour when exposed to moisture and oxygen. This harmless, natural rusting process creates a sweet taste that encourages horses to salivate, accept the bit, and increase contact. It is expected and beneficial, not a defect.
