How should I care for a red-finished collectible blade?
Updated Mar 2026
The crimson finish on these blades is a surface treatment applied over the steel, and it benefits from gentle, consistent care. Avoid direct contact with bare hands on the blade surface - natural oils from skin can degrade the finish over time. When dusting, use a soft, lint-free cloth rather than paper towels or abrasive materials. Apply a thin coat of neutral camellia oil or Renaissance Wax to the blade every few months to protect against humidity, particularly if you live in a coastal or high-moisture environment. Store or display the tanto away from prolonged direct sunlight, which can cause surface discoloration on lacquered components including the saya. Keeping the piece in its saya when not on active display also reduces dust accumulation on the fittings.
