The katana is a Japanese sword which grew to popularity during the feudal era and features a distinctly curved blade. A well-made katana was not only a functional tool, but a symbol of the samurai’s honor and discipline.
However, the sands of time only flow in one direction, meaning that any katana, at some point, is going to need cleaned or require maintenance.

Understanding the Basics of a Katana
Before you begin maintaining your katana, it is important to understand the basic components of the sword.
The blade is the most important part of the katana, and it is made of two types of steel – soft steel and hard steel. The soft steel makes up the core of the blade, while the hard steel is used to form the edge. This technique is used to give flexibility to the blade.
The other components of the katana include the tsuka (handle), tsuba (guard), saya (scabbard), and sageo (cord). Each of these components plays a crucial role in the overall function and appearance of the sword.
Cleaning a Katana
One of the most important aspects of maintaining your katana is keeping it clean.
After each use, you should wipe down the blade with a soft cloth to remove any dirt, sweat, or oil. If the blade is particularly dirty, you can use a mild soap and water solution to clean it. However, be sure to dry the blade thoroughly afterward to prevent rust from forming.
In addition to cleaning the blade, you should also clean the tsuka and tsuba. Use a soft cloth to wipe down the handle and guard, and make sure to remove any dirt or debris that may have collected in the crevices.
Sharpening a Katana
Sharpening a katana can be a complex process, and it is best to seek the guidance of an experienced professional if you are not familiar with the procedure.
Here are the general steps you can follow to sharpen a katana:
- Prepare your workspace: Clear your workspace and make sure you have a clean, flat surface to work on. Lay down a non-slip mat or towel to keep the sword from moving around.
- Clean the katana: Make sure that the katana, and the blade in particular, is clean before beginning the sharpening process.
- Remove the saya (scabbard) and tsuba (handguard): These parts can get in the way and make sharpening more difficult. Remove them carefully and set them aside.
- Secure the blade: Use a vise or sword clamp to hold the blade firmly in place. Make sure it is secure, but not so tight that it damages the blade.
- Prepare the sharpening stone: If using a water stone, soak it in water for several minutes before use. If using an oil stone, apply a thin layer of oil to the surface. If you don’t have a sharpening stone available, then alternatively, you could use sandpaper instead.
- Set the angle: If you are not experienced in sharpening, it can be helpful to use a guide rail or clamp to maintain a consistent angle. The angle will depend on the type of blade and the desired sharpness.
- Begin sharpening: Starting at the base of the blade, draw the blade along the stone in a smooth motion, keeping the angle consistent. Repeat this motion on the other side of the blade.
- Alternate sides: Continue to alternate sides, sharpening one side and then the other, until you have achieved the desired sharpness.
- Test the edge: Once you have finished sharpening, test the blade by gently cutting through a piece of paper. If it cuts cleanly, the blade is sharp.
- Clean the blade: Once you have finished sharpening, wipe the blade down with a clean cloth to remove any leftover metal particles or debris.
It is important to note that sharpening a katana requires a great deal of skill and experience, and it is easy to damage the blade if you are not careful. If you are unsure about the process, it is best to seek the advice of an experienced professional.
Polishing a Katana
Polishing is another important aspect of katana maintenance.
A well-polished blade will not only look beautiful but will also help to prevent rust from forming.
You can polish your katana using either a special polishing powder called uchiko or a soft microfiber cloth.
If you are using uchiko, make sure to apply the powder or cloth in a circular motion, and use light pressure to avoid damaging the blade. A microfiber cloth is a safer choice when it comes to blade longevity.
Oiling a Katana
To prevent rust from forming on the blade, it is important to oil your katana regularly.
You can use a special sword oil or mineral oil for this purpose. Apply a small amount of oil to a soft cloth and rub it onto the blade in a thin, even layer. Make sure to wipe off any excess oil, as too much can attract dust and dirt.
Storing a Katana
When not in use, it is important to store your katana properly to prevent damage to the blade or other components. Always keep your katana in its scabbard when not in use, and make sure that the scabbard is free of dirt or debris. You could also use a special sword bag, stand, or wall-mount to store your katana.
Avoid exposing your katana to extreme temperatures or humidity, as this could potentially cause the katana to rust. If you live in a particularly humid or wet climate, consider investing in a dehumidifier to keep the air in your storage area dry.
Regular Maintenance and Inspection
Finally, it is important to inspect your katana regularly for signs of damage or wear. Check the blade for any cracks, chips, or rust spots, and make sure that the handle and guard are secure.
In addition to regular inspections, it is also important to maintain your katana on a regular basis. Make a schedule for cleaning, polishing, and oiling your katana, and stick to it. This will help to ensure that your sword remains in top condition and that any issues are caught early.
When to Seek Professional Help
If you are unsure about how to properly maintain your katana, or if you notice any serious damage or wear, it is important to seek professional help. A trained swordsmith or katana expert can provide guidance on proper maintenance and repair techniques, and can also help to restore your katana to its original condition.
