Centaur's Blue Steel bits are made of a technologically advanced version of Black Steel, also know as traditional sweet iron.
Blue Steel oxidizes faster and easier compared to Black Steel.
Blue Steel will rust when in contact with air and humidity; surface rust tastes sweet and naturally stimulates additional saliva production, thus encouraging better acceptance of the bit by the horse.
Brass Roller Discs provide an additional comfort to certain horses by giving them something to play with, keeping their mouth quieter and more receptive to the rider’s aids.
