How should I store a carbon steel tanto with a teal saya long-term?
Updated Mar 2026
Carbon steel requires consistent care to prevent oxidation, and the saya demands its own attention as well. Store the tanto horizontally on a fitted blade stand or in a dedicated display case, away from windows where UV exposure can fade the teal finish and humidity swings can cause the wood saya to warp or crack. Remove the blade from the saya periodically — every few months is a reasonable schedule — and apply a thin coat of choji oil or a food-grade mineral oil to the blade surface, wiping away any excess before resheathing. Avoid storing the blade inside the saya for extended periods without this maintenance, as moisture trapped between blade and wood can accelerate rust. If you live in a humid climate, a small silica gel packet placed near the display case provides an additional layer of protection.
