What steel grades and construction standards are used in the spear collection?
Updated Feb 2026
Spear collectibles in this collection are built from high-carbon steel grades appropriate to serious blade collecting, with construction standards matched to the format requirements of polearm pieces. Manganese Steel appears in both Chinese overlord spear and Japanese yari pieces for its exceptional surface hardness and the visual impact appropriate to the large-format polearm blade. Damascus steel yari heads feature fold-forged layered patterning on the spear blade - the Damascus pattern visible across the spearhead creates a sophisticated surface character on what is already a dramatically large blade format. 1090 and 1095 carbon steel provide high-performance carbon steel options in the yari format, with the elevated carbon content delivering excellent blade hardness in the spear tip. 1045 carbon steel in the expandable ninjato spear hybrid delivers reliable carbon steel construction in a more compact format. Detachable spearhead configurations allow the head to be separated from the pole for storage and transport.
