The story behind the blade

Rengoku Kyojuro, the Flame Hashira of the Demon Slayer Corps, is one of the most beloved characters in Demon Slayer: the central figure of the Mugen Train arc (manga and 2020 film — the highest-grossing animated film in Japanese history). His Nichirin blade, blazing red, reflects his solar strength and generous spirit. The Rengoku Kyojuro Katana sharpened edition is a faithful replica of this iconic weapon.

The blade (nagasa approximately 70 cm) features a flame-red finish, consistent with the color of Rengoku’s Nichirin in ufotable’s anime. The uniform polish displays deep red-orange shading, reminiscent of glowing embers in a hearth.

The fittings follow Koyoharu Gotouge’s design: tsuka wrapped in interwoven red and yellow ito (the character’s signature palette), bronze-gold tsuba shaped as a stylized flame, saya lacquered in bordeaux-red with yellow shading, sun-yellow sageo, and burnished gold habaki.

An essential piece for Demon Slayer fans who love Rengoku — whose appeal is virtually universal among readers — a perfect complement for Flame Pillar cosplay (white haori with flame shading), décor for Mugen Train-themed otaku rooms, or a nostalgic gift for anyone who was moved by the film. A katana that carries Rengoku’s final words.

Intended for collection, display, and decoration only. Not designed for functional use (combat, cutting, sparring, or martial training).

✠ 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
