The contents
The box contains blade oil described as choji oil, an uchiko powder ball, a brass mekugi pin tool and rice paper. The sliding lid keeps the tools together between care sessions. A sword is not included.
The routine
A plain steel blade and a colored or decorative finish may require different products. Follow the care instructions for the specific sword. Do not assume abrasive powder is suitable for every surface or dismantle a sword just because the kit includes a pin tool.
Handling and damp conditions can affect steel even when a sword stays in a cabinet. Keep it dry and inspect it regularly. Use compatible blade oil as directed for that model, and keep oil away from textile wrapping, bags and display furniture.
Choosing your supplies
For routine exterior care, follow the sword’s instructions and leave the handle assembled unless the maker specifically calls for removal. The kit is a set of supplies, not a sharpening system or a repair for damaged finishes.
Close the oil container and keep the kit dry, upright and away from children. Keep used and clean wiping materials separate. Pair it with a soft storage bag only after the sword and its saya are ready for storage.
Steel still needs care when a sword is used only for display. You need supplies appropriate to its finish, whether kept in this kit or chosen separately. Follow the specific sword’s care instructions.
It contains powder used in some traditional blade-care routines. It can be abrasive, so do not use it on a colored or decorative finish unless the sword’s maker says it is suitable.
The product listing describes it as choji blade oil. The exact ingredient formulation is not confirmed. Use it only where it is compatible with the care guidance for your sword.
Use a product intended for blade care and compatible with the blade’s finish. Do not assume cooking oils, fragranced oils or general household products are suitable substitutes.
Routine exterior care does not automatically require disassembly. Follow the maker’s instructions and seek experienced help before removing fittings. The brass tool being included is not a reason to dismantle the sword.
