How should I store a tanto with a red tsuka to keep it looking its best?
Updated Mar 2026
Red ito (handle wrapping) is typically made from silk or cotton cord dyed to a deep crimson. To maintain the color and the tightness of the wrap, avoid prolonged exposure to direct sunlight, which fades organic dyes faster than most collectors expect. Store the tanto horizontally in its saya in a dry environment - humidity fluctuations cause the tsuka core (usually wood) to expand and contract, which can loosen the ito over time. For the blade itself, apply a thin layer of choji oil every two to three months using a soft cloth or uchiko ball, wiping away the previous coat before applying fresh oil. Never use synthetic or cooking oils as substitutes - they go rancid and damage the steel. Keep the blade away from bare-hand contact; oils from skin cause uneven patina on high-carbon steel that is difficult to correct without professional polishing.
