How should I oil and maintain a folded steel display wakizashi?
Updated Mar 2026
For a wakizashi displayed in a climate-controlled interior, a light application of choji oil every two to three months is sufficient. Apply a small amount to a soft cloth or uchiko-style ball and work it evenly across the blade surface from habaki to tip, then buff off any excess so the film is nearly invisible. Avoid silicone-based products, which can mask surface rust rather than prevent it. If the blade develops light rust spots from humidity exposure, a few passes with a lightly oiled cloth and a very fine polishing cloth can address surface oxidation without damaging the grain pattern. Never use abrasive compounds, which will permanently alter the folded steel's surface texture.
