How do I maintain a Manganese Steel spear head in a long-term display?

 Updated Feb 2026

A Manganese Steel spear head requires consistent oil maintenance to protect the carbon steel alloy from surface oxidation during long-term display. The maintenance routine is the same as for any carbon steel sword collectible: wipe the full blade surface with a soft lint-free cloth periodically to remove dust accumulation and any moisture from ambient humidity, then apply a thin coat of camellia or mineral oil to the complete blade surface and buff away excess. For a wall-mounted display piece that is not frequently handled, the oil maintenance interval can be extended compared to pieces that are regularly picked up - monthly inspection and oiling is typically sufficient for a stable-humidity display environment. Inspect the blade at the spear head connection point periodically to ensure the mounting is secure and the metal-to-pole junction remains free of moisture accumulation.
