Akagane Katana Specifications

Genuine Rayskin Saya — The Defining Feature

The saya is wrapped in genuine rayskin (samegawa) — the same material traditionally used on katana handles, here covering the entire scabbard. The gray granular texture is natural and unmistakable: no lacquer finish replicates the nodular surface of real rayskin. Every other saya in our catalog is lacquered wood, painted, or wrapped in leather. The Akagane katana saya is pure samegawa over a solid wood core. Buffalo horn kashira (end cap) and kojiri (tip) in amber-black frame the rayskin, and the red-and-white sageo provides the cord accent. If you're looking for a katana where authenticity extends to the scabbard, this is the one.

T10 Blade with Genuine Hamon

The blade is forged from T10 tool steel — tungsten-content high-carbon reaching 60-62 HRC after heat treatment. The visible hamon runs the blade's length in a notare pattern, with an amber-toned gradient near the habaki where the clay tempering created a heat-color transition in the steel. That amber zone is a natural byproduct of the quenching process — not paint, not coating — and it gives the Akagane katana blade a warm glow near the guard that fades into the cooler polished steel above.

Red Handle — Genuine Rayskin on Both Surfaces

Red cotton ito wraps over genuine rayskin on the handle — the same real samegawa material covering the saya. The gray-white rayskin diamonds flash through the red cord crossings. Genuine rayskin grips differently than synthetic: the natural nodules provide friction even when wet, and the material anchors the ito wrapping in place through texture alone. Bamboo mekugi pin the full-tang blade through the solid wood handle core. The Akagane katana uses genuine rayskin on handle AND saya — double samegawa on one sword.

Iron Tsuba & Buffalo Horn Fittings

The iron tsuba is deliberately simple — a plain dark circular disc with no ornament. On a blade where the saya's rayskin texture and the handle's red ito carry the visual identity, the guard steps back. The copper habaki provides the warm accent between blade and guard. Buffalo horn kashira and kojiri are the traditional premium fitting material — denser than lacquered wood, naturally dark, requiring no coating. The blade achieves its presence through materials, not decoration.

Akagane — Red Copper

Akagane (赤銅) means "red copper" — the Japanese name for shakudō, the copper-gold alloy used in traditional sword fittings. More broadly, aka (赤) means red — the color of life, vitality, the blood that flows when the heart beats. The red ito, red-white sageo, and warm amber habaki carry that life-color through the blade's design. The rayskin — once living tissue on a ray's body — continues the theme: organic material, genuine origin, life translated into function.

Display

Ships with a horn-style bronze stand on a dark wood base. The rayskin saya's gray texture reads as raw and natural against any background — it does not compete with surrounding décor because it does not look like décor. It looks like a weapon. The Akagane pairs with the Shirokuro (silk ito, buffalo horn — different premium material set) or the Kuroki (magnolia saya, stingray ito — different natural-material philosophy). Solo, the rayskin saya ensures no one mistakes this for a replica.

Frequently Asked Questions

Is the saya really covered in rayskin?

Yes. The entire saya is wrapped in genuine rayskin (samegawa) over a solid wood core. The gray nodular texture is natural and cannot be replicated by lacquer or synthetic materials. This is the only katana in our catalog with a rayskin-covered scabbard.

What is buffalo horn used for?

The kashira (pommel cap) and kojiri (saya tip) are made from buffalo horn — the traditional premium material for Japanese sword fittings. Horn is denser and more durable than lacquered wood, and naturally dark without requiring coating.

Is this Akagane katana sharp?

Yes. The T10 tool steel blade is hand-sharpened and functional. Handle with care, store in the saya, and check local regulations before ordering.

What is the amber color near the habaki?

The amber-toned gradient near the habaki is a natural byproduct of the clay-tempering process — heat coloring in the steel created during quenching. It is not paint or coating.

What does Akagane mean?

Akagane (赤銅) means "red copper" — the Japanese term for shakudō, a traditional copper-gold alloy. More broadly, aka (赤) means red, representing vitality and life-force in Japanese color symbolism.
