How should I maintain and store a White Wakizashi long-term?

For the blade, apply a thin coat of choji oil or light mineral oil every few weeks using a soft flannel cloth. This prevents surface oxidation, which carbon steel is naturally prone to. Avoid touching the blade with bare fingers, as skin oils accelerate rust spots. For the white saya, store the sword horizontally on a display stand in a room with stable humidity between 40 and 60 percent. Excessive dryness can crack the wood beneath the lacquer, while high humidity encourages mold. If you keep the sword in a cloth bag inside a cabinet, add a small silica gel packet to regulate moisture. Periodically inspect the mekugi bamboo pin that secures blade to handle and ensure it remains snug.
