Composition: Blue Steel (54% carbon and 46% manganese)
This bit has a rather direct action and the double joint avoids the nutcracker effect.
Blue Steel oxidizes over time creating a thin layer of rust. It naturally stimulates salivation leading to relaxed acceptance. This process of oxidation makes the mouthpiece turns from blue to a greyish brown.
Care tips: thoroughly rinse the bit with water after each use to limit residue build-up.
