The Satinox Bit line from Herm Sprenger features high quality stainless steel characterized by excellent workmanship and tested material quality. The Satinox Bits are ergonomically shaped and anatomically designed, allowing for even distribution of pressure and an anatomically correct fit between the tongue and pallet. The satin matte surface of the mouthpiece offers a pleasant feeling on the tongue. The curved shape gives the tongue plenty of room while providing an even distribution of pressure to achieve direct and precise contact.
