Waterford bitComposition: German Silver (65% copper, 23% zinc, 12% nickel) a relaxing and solid alloy. Effect: the large flat rings offer a better direction and a light lever action. The Waterford cannons split the contact points. Tips: for horses that are used to take too much contact, this bit makes them lighter on the hand. Maintenance advice: rinse the bit after each use to prevent any residue deposit and to avoid your horse to feel any discomfort.
