How to Care for Your Master Forge Blade

The Basics

1. Keep it dry. Moisture is the enemy of carbon steel. Wipe the blade down after every handling.
2. Keep it oiled. A thin layer of blade oil (mineral oil, camellia oil, or gun oil) prevents rust.
3. Keep it sheathed. Always store in the saya or sheath that came with it.
4. Keep it somewhere dry. Humidity causes rust. Avoid basements and bathrooms.

After Every Use

Whether you used your blade for cutting, practice, or just took it out to admire, do these three things:

• Wipe the blade clean with a soft, lint-free cloth
• Apply a thin coat of oil along the entire blade (front and back)
• Return it to the sheath or display

Takes 60 seconds. Saves your blade for a lifetime.

How to Oil a Carbon Steel Blade

1. Lay the blade flat on a clean surface
2. Put 3–5 drops of blade oil on a soft cloth
3. Wipe the blade from spine to edge (away from your hand)
4. Flip, repeat
5. Wipe off any excess

Recommended oils: Camellia oil (traditional for katana), mineral oil (food-safe, good for kitchen damascus), or gun oil (general purpose).

Never use: Cooking oils like olive or vegetable — they go rancid.

How to Handle Light Rust

If you see light surface rust (orange-brown dots):

1. Rub gently with a soft cloth and a few drops of oil
2. For stubborn spots, use very fine steel wool (0000 grade) with oil, gentle pressure
3. Wipe clean
4. Re-oil the entire blade

Don't panic. Light rust on carbon steel is normal and removable.

How to Sharpen Your Blade

For katana and swords: Do not sharpen yourself unless you are trained. Take it to a professional sword polisher or contact us for a referral.

For damascus knives and machetes: Use a quality whetstone (1000 grit for edge repair, 3000–6000 for finishing). Maintain the existing bevel angle. Go slow and use light pressure.

For daily edge maintenance: A leather strop with polishing compound keeps the edge razor-sharp without removing steel.

Storage

Short-term: In the sheath, in a dry room, away from direct sunlight.

Long-term: Oil the blade heavily, wrap in a lint-free cloth, store in the sheath in a dry place. Check every 2–3 months and re-oil.

Avoid:

• Leather sheaths for long-term storage (leather holds moisture)
• Plastic bags (trap humidity)
• Humid rooms (bathrooms, basements, uncontrolled garages)

What Not to Do

• Don't touch the blade with bare fingers — skin oils cause corrosion
• Don't store uncleaned after use
• Don't use in saltwater environments without immediate cleaning
• Don't clean with water only — always oil after
• Don't hit hard surfaces (bone, stone, nails) unless the blade is built for it
