A Curbgag bit made of mild steel with a blue patina and a double-jointed French Link mouthpiece.
✨ Key features
- ✔ Sweet Iron is mild steel blued during manufacturing by heating. When exposed to moist air and saliva, it develops a surface oxidation with a sweet taste that naturally stimulates salivation: the horse chews more and accepts the bit more readily.
- ✔ Double-jointed mouthpiece with a figure-eight-shaped central plate that distributes pressure evenly across the tongue. Its finer edges make the action slightly sharper than that of a standard double-jointed mouthpiece, and the plate is angled at 45° so it lies flat on the tongue.
- ✔ A combination of a Pelham and a loose-ring gag: a loose ring with two holes on each side, through which a leather strap passes. The pressure points are the chin and poll. It can be used with one or two reins.

🐎 Why choose this product?
The figure-eight plate distributes pressure evenly across the tongue: this is the standard double-jointed mouthpiece, the one to try when a single joint causes discomfort.
🧴 Usage advice
⚠️ Bit size is given in millimetres: it is the width of the mouthpiece from one ring to the other. A 125 measures 12.5 cm. Measure your horse's mouth with a bit measuring tool, or measure the bit it currently wears: if it is too wide, the bit moves around and pinches; if it is too narrow, it tightens the corners of the mouth. ⚠️ Combined leverage and curb-chain action: reserved for experienced riders. ⚠️ The blue colour turns silver-grey or brown-grey with use, and an orange film appears when the bit is left unused: this is normal Sweet Iron behaviour, not a defect. A wipe with a damp cloth is enough to remove it. This oxidation is not harmful.
