What steel grades are used for Chinese great sword construction?
Updated Feb 2026
Chinese great sword formats in this collection use 1090 carbon steel for polearm Guan Dao construction, Manganese Steel for dragon-design dao and overlord spear components, and 1045 carbon steel for accessible extended dao formats. 1090 carbon steel provides the higher carbon content appropriate for the specific hardness requirements of crescent blade and polearm blade construction. Manganese Steel's exceptional surface hardness makes it ideal for the dramatic surface treatments and dragon design details that characterize premium Chinese great sword pieces - the hard surface holds decorative treatments with greater consistency than softer steel grades. 1045 carbon steel provides the accessible foundational tier for Chinese extended dao with correct full-tang construction and genuine blade hardness appropriate to the grade.
