How should I store and maintain a Sekiro display katana?

Carbon steel - regardless of grade - will develop surface oxidation if left unattended in humid environments. For display, apply a light coat of choji oil or mineral oil to the blade every two to three months, wiping it on with a soft cloth and buffing off the excess. Store the sword horizontally on a proper katana stand, or hang it on a wall mount with the blade edge facing upward, as is traditional. Keep it away from coastal air, kitchen humidity, or any environment where moisture concentrates. When handling, wear cotton gloves or hold the blade by the spine - fingerprint oils accelerate spotting on polished carbon steel. The hardwood saya provides meaningful protection during storage; always sheathe the blade when it's not being displayed.

Is full-tang construction important for a display katana?

Updated Mar 2026

For a collectible sword intended for handling, rotation on a display stand, and close examination, full-tang construction matters considerably. A full-tang blade means the steel extends through the entire length of the tsuka (handle), secured by one or more mekugi (bamboo or steel pins) passing through both the tang and the handle core. This creates a unified structure with no mechanical joint between blade and handle - the point of failure common in rat-tail or partial-tang construction. When a collector lifts the sword, adjusts its angle, or removes it from a wall mount, the full-tang assembly ensures the blade and handle respond as a single rigid unit. Over years of display and occasional handling, this structural integrity preserves the alignment between blade, habaki, and saya, which also protects the engraved surface from incidental contact damage.
