We love the Korsteel Double Hinged Uxeter Kimberwicke Bit because the double-jointed mouthpiece works on the tongue, mouth corners, and bars, slotted rings allow use as a snaffle. The copper roller helps keep the horse's attention to the rider while double hinge action is helpful on horses with a low pallet. The double hinge design keeps the middle of the bit from hitting the roof of the horse's mouth when reins are used. Dual slots offer a range of leverage to help with steering and control through the curb chain.
