Sultan Series swords are made from Bulat / Wootz steel, one of the most advanced methods of swordsmithing and blacksmithing. This method, later known as Damascus steel, was used by Turks and some Eastern nations for centuries to produce their swords. Steel  is produced by melting in a clay crucible from scratch, and the sword is crafted through rigorous forging. Patterns are created on the sword's surface, and these patterns derive from the steel's own impurities and structure unlike pattern welding. This series is the highest-level series, requiring extensive time and effort. Like the other series, it also includes three main periods and sub forms and is fully customizable.
