TRUE Finishes & Coatings
Black Nitride, known as "Melonite," provides a deep, hardened, jet-black finish from within the steel, whereas PVD offers various colors with varying wear resistances, including the less durable TRUE Blue. TRUE Precision also features a customizable Satin Stainless finish, which is corrosion-resistant but benefits from regular maintenance.
