The Superior Kiri cleaning kit is the top-of-the-range cleaning box for Japanese blades.

Presented with an elegant traditional box in Kiri 桐箱 (Paulownia wood), this box keeps accessories away from moisture. It is an ideal and complete high-end case for the maintenance of steel blades.

This box contains the following:
- 1 Small bottle of Choji Abura 丁子油: Premium clove oil
- 1 Traditional Nuguigami sachet 拭紙: with 2 washi sheets
- 1 Flannel フランネル: Square of soft felted fabric
- 1 Grand Uchiko 打粉: Fine powder abrasive buffer
- 1 Mekuginuki 目釘槌: Hammer with flush pin for disassembly of Mekugi

Use:
Prepare a clean and soft work surface on a fabric surface. If necessary, completely disassemble your sword by removing the Mekugi with the Mekuginuki. Cut out and use a piece of Nuguigami to remove waste and old oil still present on the blade. Dab the blade with the Uchiko on the length with a spacing of about 5 cm. Use another piece of Nuguigami to remove impurities and surface oxidation by rubbing the powder on the blade with Nuguigami. Remove all Uchiko powder from the blade. Finally, place a few drops of Abura on the flannel and cover the entire blade (except Nakago) with a thin layer of oil.

Caution: The use of Uchiko, an abrasive powder based on polishing stone, is not recommended on Zamak iaito.
