By purchasing from Katana Corp, you acknowledge and agree that:
For full details, please refer to our Terms of Service.
To maintain your katana's appearance and performance over time, we recommend:
- Regularly wiping the blade with a soft cloth to remove fingerprints and moisture.
- Applying a light coat of choji oil to prevent rust (for carbon steel blades).
- Storing the sword in a dry place, preferably inside its saya.
- Avoiding direct contact with hard surfaces to preserve sharpness and finish.
For more care tips, check our full maintenance guide in the FAQ section.
Every katana we offer carries the essence of centuries-old craftsmanship.
More than just a weapon, the katana symbolizes discipline, honor, and mastery.
Our artisans draw inspiration from traditional forging methods to ensure each blade reflects the spirit of the samurai - strength, precision, and soul.
Owning one is not just about aesthetics - it’s about carrying a piece of that legacy.
This katana is designed to offer a perfect balance between blade and handle.
Its ergonomic tsuka (handle) allows a secure two-handed grip, while the weight distribution ensures smooth, fluid movement.
Sold for collection and display. Handle carefully when placing on a stand or carrying out maintenance.
Demon Slayer / Rengoku
The flame-shaped guard gives this Rengoku katana away at a glance. A red-and-black blade, white handle and patterned white scabbard carry the fiery look through the whole piece, inspired by Demon Slayer's Flame Hashira.
The blade
A red flame pattern follows the dark blade, with a kanji detail near the guard. The blade is listed as 1060 carbon steel, sharpened and full tang. Its color is a fixed part of this replica's finish. The close-ups let you compare the pattern with our silver-bladed Tanjiro model before choosing between them.
The fittings
The sculpted iron guard uses orange, dark and yellow details to outline the flame shape. White cotton wraps the handle, while the white lacquered wooden saya carries black geometric lines and orange fittings. The contrast keeps the design readable whether the sword is displayed sheathed or beside its scabbard.
Kyojuro Rengoku is the Flame Hashira in Demon Slayer and a central character in the Mugen Train story. His flame-themed sword is closely tied to that identity. This replica brings those visual cues into a steel display piece, with the actual finish and fittings shown in the product photos.
In your collection
Rengoku and Zenitsu make a colorful pairing, with flames on one blade and lightning on the other. Our Tanjiro model offers another flame-shaped guard but a silver blade and darker fittings. Compare those details rather than assuming that every Demon Slayer replica follows the same design.
Keep the white wrap clean and the blade dry. Follow the Care & Maintenance instructions for protecting the steel, and avoid abrasive cleaning on the red finish or kanji detail. Place the sword and saya securely on a stable stand, with the sharp edge out of reach.
It is Rengoku's Nichirin sword from Demon Slayer. This replica follows the flame-themed look associated with the Flame Hashira, using a red-and-black blade and flame-shaped guard.
This model has a red flame-patterned blade, white handle and white patterned saya. Our Tanjiro katana has a polished silver blade and black-and-red fittings. Both have their own product photos and specifications.
The colors reflect Rengoku's flame theme. On the replica, they are the blade's fixed finish. The steel does not change color or produce a flame effect.
Yes. The blade is 1060 carbon steel, sharpened and full tang. It is sold for collection and display, not as a foam or blunt costume sword.
The listed overall length is 105 cm, about 41 inches, with a 72 cm blade and a 30 cm handle. Use those dimensions when choosing a space for it.
No. The flame design is a static finish on steel. There is no lighting, sound or color-changing feature in this model.
The katana, matching white scabbard and an ornate display stand are included. Other swords and background accessories are sold separately.

Customer reviews
Good sword, small issue on arrival
Saya mouth was slightly loose when I got it, fitting tape sorted it. Balance is great though. People at my dojo always ask about it.
Way better than I expected
Hamon is clean, handle wrap tight, saya closes solid. Came in a wooden box. No complaints at all for the price.
Got it as a gift, he was speechless
Bought for my boyfriend who does iaido. He said the fit and finish were legit. I knew nothing about swords, site made it easy to pick.
Nice blade but took 2 weeks to arrive
Damascus looks great. Shipping to Portland took forever and tracking was dead for a week. Quality is there, logistics need work.
Third order, still no complaints
Ordered three times over two years. Always well packed, matches the photos. Support replied same day. Will keep coming back.
