Owning a sword is not just about its historical value or aesthetic appeal; it’s also about preserving its craftsmanship. Proper care ensures that your sword remains pristine, whether using it as a weapon, a collector’s item, or a decorative piece. This guide will walk you through everything you need to know about caring for your sword.
Why Sword Care is Essential
Caring for your sword is essential for several reasons:
- Rust Prevention: Keeping your blade clean and oiled helps prevent rust.
- Longevity: Proper care ensures your sword will last for generations.
- Safety: A well-maintained sword is safer to handle and use.
Proper sword care applies to functional, decorative, and antique swords. Whether using a katana or a European longsword, these steps will help preserve its integrity.
What You’ll Need for Sword Care
Before you start, gather the following tools:
Essential Tools:
- Soft lint-free cloths are used to wipe down the blade.
- Rubbing alcohol to remove fingerprints and smudges.
- Sword oil (or a specialized blade oil) to protect against rust.
- Rust eraser for minor rust removal.
- Leather gloves to avoid transferring oils from your hands.
Optional Tools for Advanced Care:
- A sharpening stone (such as a waterstone) is used to sharpen the blade.
- Silica gel packs to control humidity in storage.
Step-by-Step Sword Care
1. Quick Care (After Every Use or Handling)
After each use or handling, cleaning and preparing your sword for storage is crucial.

Pro Tip:
Always wipe down your sword after use to prevent moisture buildup. Even a small amount of moisture can cause rust over time.
Step-by-Step:
- Set up a clean workspace: Choose a dry, clean area free from dust or dirt.
- Wipe the blade: Use a dry cloth to wipe off fingerprints, dirt, or moisture.
- Remove smudges: Dampen a cloth with rubbing alcohol and gently clean stubborn marks.
- Oil the blade: Apply a thin layer of oil to protect against rust. Wipe off any excess oil to avoid attracting dirt and dust.
- Store safely: Place the sword in a sheath or holder, away from excessive moisture.
Caution:
- Never store your sword in plastic wrap; it can trap moisture and promote rust.
2. Monthly Maintenance
At least once a month, perform a deeper inspection and cleaning to ensure your sword stays in top condition.

Pro Tip:
Perform a complete inspection under light to catch minor issues like rust or dullness before they worsen.
Step-by-Step:
- Inspect the blade: Check for rust, chips, or cracks under a bright light.
- Clean the fittings: Use a soft brush to clean any decorative parts of the sword, such as the guard or pommel.
- Re-oil the blade: Depending on the blade material (carbon steel or stainless steel), reapply oil to protect the blade.
Caution:
- Be mindful of over-oiling your sword. Too much oil can attract dust and debris, dulling the blade.
3. Deep Care (When Needed)
Sometimes, your sword may need more intense care. This is typically required only if you notice significant issues like rust or damage.

Pro Tip:
Use a rust eraser or fine steel wool to remove minor rust spots gently. Always test on a small area first.
Step-by-Step:
- Remove surface rust: If rust appears, gently buff it off with a rust eraser or fine steel wool.
- When to seek professional help: If the rust or damage is widespread, it’s best to consult a professional swordsmith.
Caution:
- Avoid using abrasive materials if the rust is deep. These can damage the metal and affect the sword’s structure.
4. Proper Storage
Storing your sword properly is just as important as cleaning it. Incorrect storage can lead to long-term damage.

Pro Tip:
Use silica gel packs in your storage area to help control humidity, which can prevent rust.
Step-by-Step:
- Maintain ideal humidity: Keep your sword in a controlled environment where humidity is not too high or too low.
- Avoid leather sheaths long-term: Leather can trap moisture against the blade and encourage rust.
- Store katana-style swords horizontally: For katana swords, store them horizontally, with the edge slightly facing away from the wall to avoid accidental damage.
- Do not use plastic wrap: It can trap moisture and encourage corrosion over time.
Caution:
- Storing your sword in a damp location is a considerable risk for rust. Avoid basements or bathrooms where moisture levels fluctuate.
5. Sharpening Basics (If Applicable)
A sharp blade not only looks better but also performs better.

Pro Tip:
Sharpen only when necessary: Frequent sharpening can wear down the blade. Sharpen only when the edge becomes noticeably dull.
Step-by-Step:
- Tools needed: Use a sharpening stone (like a waterstone) for a fine, precise edge.
- Correct sharpening angle: Follow the manufacturer’s recommended sharpening angle (usually between 20-25 degrees).
- Clean the blade: Wipe off any metal dust or residue after sharpening.
Caution:
- If you’re not confident in sharpening your sword, hiring a professional is better to avoid damaging the blade.
6. Good Habits to Prevent Problems
In addition to regular care, there are habits you can adopt to prevent issues from arising.

Pro Tip:
Wear gloves to avoid leaving fingerprints and oils on the blade when handling your sword.
Habits to Follow:
- Avoid food or plant contact: Acids from food and plant matter can harm the blade.
- Store in dry conditions: Keep your sword in a dry, clean area to prevent moisture-related issues.
- Don’t use WD-40 long-term: While WD-40 is great for cleaning, it should not be used for long-term oiling, as it can attract dirt.
Caution:
- Never touch the blade unnecessarily. Even a small amount of oil from your hands can cause damage over time.

FAQs About Sword Care
Can I use cooking oil on my sword?
While cooking oil can work in a pinch, it’s not ideal. It can become sticky over time. Use specialized sword oil instead for better results.
How do I oil stainless steel swords?
Stainless steel swords need less frequent oiling, but applying a light coat of oil every few months can help maintain their appearance.
What if I find rust spots?
Small rust spots can usually be removed with a rust eraser. If the rust is deep or widespread, it’s best to consult a professional.
Is it safe to store my sword in a leather sheath?
Storing in a leather sheath is fine for short periods, but use a padded container for long-term storage to avoid moisture buildup.
