Inspired by the original meteorite ring, the "KNOX" Ring is the same beautiful ring CNC machined out of 4142 steel. This begins as a single billet, then get precision milled to its final stage. After which it gets tumbled to remove any burs, hand polished, then sand blasted. This entire process is carried out by the same hands from start to finish to insure quality the whole way. Once the metal has been meticulously inspected, It goes out for a black nitride process. During this process, a two-part surface layer is formed, an outer iron nitride layer with a nitrogen diffusion layer below it. Providing strength and corrosion resistance.
