The story behind the blade

The Seiryu — the Azure Dragon — is the guardian of the east among the Four Celestial Spirits: ruler of the forest, spring, and the element of wood. Its image appears on the east-facing walls of imperial temples and palaces. In Kyoto, the Kiyomizu-dera complex, dedicated to the Seiryū-gawa sanctuary, still bears its name. The Katana Seiryu pays tribute to this eastern draconian figure.

The T10 steel blade (60–62 HRC hardness, nagasa approximately 27.5 in.) carries an authentic undulating hamon that recalls the sinuous outline of the dragon in flight. The differential tempering leaves the transition line between the hardened edge and the flexible spine visible — an organic quality unique to this process.

The fittings take the azure dragon’s palette: sky-blue ito over samegawa, a dark alloy tsuba with a coiled dragon-body motif (a classic pattern), a saya lacquered in deep sky blue with silver highlights, and navy-blue sageo. Patinated silver habaki.

A display piece for those who favor luminous palettes, well suited to east-facing rooms with morning light, and a gift for admirers of comparative mythology or anyone who has visited Kiyomizu-dera. A katana that brings the lightness of an eastern sky creature into your home.

✠ Sword US ✠

Every blade, three stages

Time-honored craft. Masterful gesture. A one-of-a-kind, hand-forged piece built to last.

Forging

The blade takes shape beneath the hammer. Each layer of steel is folded and re-welded under heat to create a core that is both strong and flexible.

Tempering

The steel is brought to high temperature, then quenched rapidly: this fast cooling hardens the edge and reveals the hamon, the wavy line that runs along the blade.

Polishing

The smith hand-polishes the blade with natural stones of increasing grit, revealing its luster, its edge, and the soul of the steel.

Frequently asked questions

How to care for your blade

After every use, wipe the blade with a soft, dry cloth to remove fingerprints. Carbon steel reacts to humidity and the natural acids on your skin: a light coat of mineral oil (Ballistol or camellia oil) applied once or twice a month protects against corrosion for the long term. For extended storage, keep the sword outside its scabbard, in a dry place away from direct sunlight. If a rust spot appears, gently buff it with a very fine stone and oil it immediately. A well-cared-for blade lasts through generations.

Is this sword sharpened?

Our carbon steel blades (1045, 1060, T10, Damascus) all ship sharpened by our partner smiths. Stainless steel blades (420, 440), made for collection and display, are not sharpened.

What are the shipping times?

Ships within 7 business days for in-stock items. If the item is on preorder, the expected date is shown at the top of the page.

Can I return my order?

Yes, you have 30 days from delivery to return it.

Is it legal to own a sword?

Yes — owning a sword in your home is perfectly legal in the United States, whether for collection, decoration, historical reenactment, or sport practice (HEMA). Carrying it in public is restricted by state and local laws: a sword is considered a bladed weapon, and transporting it outside your home without a legitimate reason (event, training, transport to a club) may be subject to local regulations. Our pieces ship in a scabbard and protective packaging suitable for initial transport from our warehouse to your home.

Is payment secure?

Yes, completely. Our store is protected by an SSL certificate (https://) that encrypts all communications between your browser and our site. Payments are processed directly by Stripe and PayPal — we never have access to your card details (card number, CVV, expiration date). Your information is shared only between you and the payment processor, never through our servers.

Free returns within 30 days
