We love this Shires Sweet Iron Copper Tom Thumb Bit because it promotes salivation.
With a sweet iron mouthpiece designed to produce a sweet taste and encourage salivation as it oxidizes. The addition of copper ribs helps to prevent the horse from taking too much contact, a good deterrent for horses that tend to take hold.
The cheeks give this bit a lever-action, creating some poll pressure while the double-jointed mouth, with rollers is good for horses with busy mouths.
