What steel types are the o-naginata blades in this collection made from?

The o-naginata in this collection use T10 folded clay-tempered steel and Damascus pattern-welded steel. T10 is a high-carbon tool steel with a carbon content around 1.0 percent, which allows it to achieve a very hard edge zone through differential clay tempering while maintaining a tougher, more flexible spine. When clay-tempered, T10 produces a well-defined hamon - the visible line along the edge created by the boundary between the hardened edge zone and the unhardened body - that is clearly visible on a properly polished blade. Damascus steel in this context is pattern-welded steel made by forge-welding multiple steel types together and working the billet through twisting, folding, and drawing until the grain layers create flowing visual patterns revealed by acid etching. Both materials produce naginata blades with significant surface visual character and the weight and balance profile appropriate for a display collectible at this scale. The marble and dark finishes visible across the collection correspond to the surface treatment and finish of each specific blade.

How should I display and maintain a marble naginata long-term?

A horizontal wall mount or a vertical floor stand both work well for naginata, though horizontal mounting distributes weight more evenly across the shaft. Keep the piece out of direct sunlight to prevent UV fading of the lacquer. For blade care, apply a thin coat of choji oil every two to three months using a soft cloth, wiping in one direction from spine to edge. The marble-finish saya can be gently wiped with a dry microfiber cloth; avoid chemical cleaners, which may cloud the lacquer layers. In humid climates, consider adding silica gel packets near the display area to keep ambient moisture below 55 percent, which protects both the steel from oxidation and the lacquered wood from swelling.

How should I store and maintain a real hamon naginata?

High-carbon steel blades—whether T10 or Damascus—require periodic oiling to prevent oxidation, especially in humid environments. Apply a thin coat of choji oil or food-grade mineral oil to the blade every one to three months, wiping off any excess with a clean soft cloth. Store the naginata horizontally on padded wall mounts or in its saya with the edge facing upward to avoid pressure on the hamon area. Avoid display near windows with direct sunlight, which can fade lacquered saya finishes over time. Never store in an airtight sealed case without a silica gel desiccant packet, as trapped humidity accelerates surface rust even on well-oiled blades. Handle the blade only with clean cotton gloves—fingerprint oils are mildly acidic and will etch high-carbon steel if left unaddressed.

How should I store a lacquered saya naginata for long-term preservation?

Long-term storage of a lacquered saya naginata requires controlling three main factors: humidity, contact abrasion, and light exposure. Lacquered surfaces are sensitive to rapid humidity changes, which can cause the finish to craze or chip — maintaining a stable relative humidity between 45% and 55% is ideal. The blade itself should be lightly coated with a thin film of choji oil or a mineral-based blade oil before storage to prevent oxidation, particularly on high-carbon steels like T10. Avoid storing the piece in a sealed synthetic bag, which can trap moisture. For display, keep the naginata away from direct sunlight and halogen lighting, both of which can fade lacquer pigmentation over time. A horizontal wall mount or padded cabinet rack distributes weight evenly and prevents warping of the wooden haft.

What should I know about displaying a naginata at home?

Updated Mar 2026

Naginata typically range from 150 to 220 cm in total length when fully assembled, so horizontal wall mounts or dedicated floor-standing polearm racks are the most practical display solutions. Avoid placing the piece in direct sunlight for extended periods, as UV exposure can fade lacquer finishes over time. For the blade itself, a light application of choji oil or a neutral camellia oil every few months will prevent surface oxidation - apply with a soft cotton cloth and wipe away any excess to avoid residue buildup. Store or display in a climate-controlled environment where humidity stays below 60%, as high moisture accelerates rust formation on high-carbon steel. When removing the blade from the saya for maintenance, always handle the mune (spine) rather than the edge, and use a clean cloth as a barrier.
