Blade Care Guide

Every SwordageForge blade is built to last — with proper care.

**A blade is not just steel.
It is discipline, balance, and time.**

Daily Care

After each use, always clean the blade surface.

Use a soft, dry cloth to remove:

— Moisture

— Fingerprints

— Dust

Even small traces of sweat can lead to corrosion over time.

Oiling the Blade

Apply a thin layer of oil regularly to protect the steel.

Recommended oils:

— Mineral oil

— Choji oil (traditional sword oil)

Use a clean cloth or paper to spread evenly across the blade.

⚠ A light coating is enough — do not over-oil.

Rust Prevention

High carbon steel is strong and sharp, but also more prone to rust.

To prevent oxidation:

— Keep the blade dry at all times

— Avoid touching the blade with bare hands

— Store in a low-humidity environment

If rust appears, remove it immediately using proper tools.

Proper Storage

Store your sword in a safe and stable environment.

— Keep away from moisture

— Avoid extreme heat or cold

— Store horizontally or with the edge facing upward

— Keep out of reach of children

For long-term storage, apply oil before sheathing.

Handling

Always handle with care and awareness.

— Never touch the edge directly

— Maintain a firm and controlled grip

— Do not swing in uncontrolled environments

A blade demands respect at all times.

Maintenance

Over time, your blade may require maintenance.

— Sharpening should be done by experienced individuals

— Do not attempt aggressive polishing

— Avoid using improper tools

Improper maintenance may permanently damage the blade.

What to Avoid

— Water exposure

— Acidic substances

— Contacting hard materials (metal, stone, etc.)

— Improper storage inside damp sheaths

These can significantly reduce the lifespan of the blade.

Care During Practice

If used for practice with soft targets:

— Clean immediately after use

— Dry completely before storage

— Reapply oil after each session

Final Note

A well-maintained blade will last for generations.

Neglect it, and even the finest steel will fade.

**Care for the blade,
and it will serve you in return.**
