How should I maintain a 1045 tanto displayed at home?
Updated Mar 2026
Apply a thin coat of choji oil or food-grade mineral oil to the blade every two to three months using a soft, lint-free cloth. This prevents surface oxidation, which carbon steel is more susceptible to than stainless alloys. Avoid touching the blade surface directly with bare hands, as skin oils accelerate rust spotting. Store or display the tanto away from direct sunlight and high-humidity areas - coastal homes or basements may require more frequent oiling. When placing the tanto on a display stand, orient it traditionally with the edge facing upward to distribute pressure evenly along the habaki and saya mouth.
