Product Details
Twisted-Grain Damascus Katana — Spiral Forged, Never Repeated
A blade that carries its lineage on its skin. The twisted-grain Damascus steel is built through a layered marriage of multiple steels, folded and torqued at the forge until the grain corkscrews into a signature spiral — each revolution unique, each blade a one-off that no craftsman could reproduce exactly. Torch it purple and the pattern deepens, the violet-baked finish sinking into every twist and fold like ink into paper.
The edge lands at 60 HRC — hard enough to hold its bite, but backed by the composite give of Damascus construction so it won't shatter under stress. In hand, the taper tells the rest of the story: 3.2 cm at the habaki, narrowing to 2.6 cm toward the kissaki, driving the balance point back toward the grip where it belongs.
Imported ebony for both tsuka and saya — dense, dark, cool to the touch, a wood that has meant seriousness in Japanese bladesmithing for centuries. Copper fittings bridge the transitions with warmth against all that darkness. At just under 1.4 kilograms, the weight lands where tradition says it should: heavy enough to feel, light enough to forget.

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
— Cutting hard materials (metal, stone, etc.)
— Improper storage inside damp sheaths
These can significantly reduce the lifespan of the blade.
For Practical Cutting
If used for cutting practice:
— 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.**
