Warm, sweet iron mouthpiece with copper rollers on the middle link, and copper nodules on the bars. 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. Loose ring.
Very popular bit that encourages the horse to salivate and helps prevent leaning.
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.
