Demon Slayer Sword Real metal Rengoku Sword Anime Sword Full Tang Blade

Rengoku Sword – T10 Steel Demon Slayer Nichirin Katana | Full Tang

Inspired by Kyojuro Rengoku, the Flame Hashira from Demon Slayer: Kimetsu no Yaiba, this handmade Rengoku sword combines the unmistakable flame-themed appearance of his Nichirin katana with real Japanese-style sword construction.

The sword features a hand-forged T10 high-carbon steel blade, full tang construction, a distinctive flame-style tsuba, white handle wrapping and a matching red-and-flame saya.

Designed for Demon Slayer fans who want more than a lightweight costume prop, this Rengoku katana can be ordered hand sharpened or left unsharpened for collection, display and cosplay purposes.

Inspired by Kyojuro Rengoku – The Flame Hashira

Kyojuro Rengoku is one of the most recognizable characters in Demon Slayer: Kimetsu no Yaiba and is known as the Flame Hashira.

His Nichirin katana reflects that identity through its bold flame-inspired color scheme, distinctive sword guard and dramatic red-and-yellow details.

This HanBon Forge version recreates that visual character while replacing lightweight costume materials with a real T10 carbon-steel blade and full tang construction.

The result is a Rengoku sword designed for collectors who want the appearance of the anime sword combined with the feel and structure of a real Japanese-style katana.

Hand-Forged T10 High-Carbon Steel Blade

The blade is forged from T10 high-carbon steel, a material widely used for Japanese-style swords because it can provide good hardness, edge retention and durability when properly heat treated.

Unlike inexpensive decorative Demon Slayer swords made from thin stainless steel, aluminum or plastic, this model uses a real carbon-steel blade.

Each blade is individually forged, shaped, polished and assembled before shipment.

Customers may select a hand-sharpened edge or choose an unsharpened blade for display and collection.

Full Tang Construction

This Rengoku katana features full tang construction, meaning the blade tang extends into the handle rather than ending immediately behind the tsuba.

This gives the sword a stronger and more substantial internal structure than the simplified or short tang construction found on many inexpensive anime swords.

For collectors comparing real-steel anime swords with decorative replicas, full tang construction is one of the most important differences.
