Snaffle with HBT Shank Stainless steel HBT shanks where the bottom of the shank curves slightly toward the rider's hands. Good for riders with over active hands. 3/8" snaffle mouthpiece applies downward pressure on the tongue and collapses on the bars while the joint drives into the center of the tongue. Sweet iron has a sweet taste as it slowly rusts encouraging the horse to salivate. Small strips of copper are placed in the 5" mouthpiece to also encourage salvation. Level 1.
