Maintenance Kit

The Sword Maintenance Kit comes in a lightweight wooden storage box and includes all the essential tools needed for regular blade maintenance. The Uchiko powder ball contains fine polishing powder and is gently tapped along the blade to loosen old oil and surface impurities. The residue is then removed with the included soft microfiber cloth. Finally, apply a thin layer of clove oil to protect the blade against rust and corrosion.

Regular maintenance helps prevent fingerprints, moisture damage, and other stains that can permanently affect the blade's finish. This maintenance kit is an essential accessory for collectors, Iaido practitioners, and sword enthusiasts alike.

Clove Oil (Tsubaki or Clove Oil)

The oil protects the blade from rust by forming a thin protective barrier against humidity and moisture in the air. As the protective film gradually evaporates over time, it is recommended to reapply the oil at least once a month.

Uchiko Powder Ball

The Uchiko powder ball contains fine polishing powder. By gently tapping both sides of the blade, it loosens old oil, fingerprints, and fine contaminants. When used together with the microfiber cloth, it helps restore a clean and polished blade surface.

Microfiber Cloth

The soft microfiber cloth is used to remove the Uchiko powder, oil residue, fingerprints, and other contaminants from the blade. It is also ideal for applying a thin, even coat of maintenance oil across the entire blade.

Brass Mekugi Remover (Mekuginuki)

The brass Mekuginuki is used to remove the bamboo retaining pins (Mekugi) from the sword handle, allowing the sword to be safely disassembled for maintenance. The brass hammer head can be unscrewed from the handle for use.

Sword Maintenance Instructions

Clean and maintain your sword after every use, whether it has been used for Iaido practice, Tameshigiri, or is simply displayed as part of your collection.

1. Remove Old Oil

Use the microfiber cloth to wipe the blade thoroughly from the tip toward the handle, removing old oil and light surface contamination.

2. Apply Uchiko Powder

Gently tap both sides of the blade with the Uchiko powder ball. The fine polishing powder helps lift old oil and dirt from the blade's surface.

3. Wipe the Blade Clean

Carefully wipe away all Uchiko powder using the microfiber cloth. Repeat the process if necessary until the blade is completely clean.

4. Apply Fresh Oil

Apply a small amount of clove oil to the microfiber cloth and spread it evenly over both sides of the blade, working from the tip toward the handle. Only a very thin protective film should remain on the blade.

5. Regular Maintenance

Every 3–4 months, it is recommended to disassemble the sword and clean the tang (Nakago) in the same manner before applying a light coat of oil.
