Forging the Infinite Reach: An Engineering Analysis of the 26cm "Nagakiba" Replica
In the Lands Between, reach is king. Any Tarnished who has faced an invader wielding the Nagakiba knows the specific anxiety of trying to roll away from a blade that seems to stretch across the entire map. It is not just a Katana; it is an Odachi—a "Great Sword" in the clothing of a nimble blade.
But shrinking an in-game model that is notoriously absurd in length (spanning roughly 2.5 meters in-game) down to a desk-friendly scale presents a unique manufacturing challenge. How do you maintain that iconic needle-like profile without the replica becoming fragile or top-heavy?
At BlacksmithSONG, we approached the Nagakiba differently from our all-metal collection. Here is the technical breakdown of our 26cm Nagakiba replica, and why its hybrid construction makes it the definitive miniature for the Bloody Finger Hunter.
⚒️ Key Specs at a Glance
-
Total Length: 26cm (Currently the longest katana profile in our inventory).
-
Net Weight: 47g.
-
Blade Material: Electrostatic-plated Zinc Alloy (Rigid & Rust-proof).
-
Hilt & Scabbard Material: High-strength Polymer (For balance and mechanism precision).
-
New Feature: Upgraded internal snap-fit retention system.
The "Washing Pole" Dilemma: Why Hybrid Materials?
Unlike many of our fully Zinc Alloy replicas, the Nagakiba utilizes a Hybrid Construction Method.
The blade itself is forged from our signature Zinc Alloy, ensuring the metal glint, cold touch, and rigidity required for a premium collectible. It maintains a razor-straight profile despite its extreme 26cm length, resisting the "bowing" effect common in softer metal toys.
However, for the Scabbard (Saya) and Handle (Tsuka), we opted for high-grade molded plastic. Why?
-
Weight Distribution: A 26cm solid metal scabbard would make the replica excessively heavy and difficult to display on standard stands without tipping over.
-
Detail Precision: The complex texture of the teal handle wrapping (Tsuka-Ito) and the gold guard (Tsuba) benefits from the sharp molding capabilities of polymer.
Engineering Upgrade: The "Snap-Fit" Mechanism
We listen to the community. A common issue with long-blade replicas is that gravity works against them—when displayed vertically or inverted, loose blades tend to slide out of their scabbaths.
For this Nagakiba iteration, we have engineered a Snap-Fit Retention System inside the plastic scabbard.
-
The Mechanism: A subtle internal latch catches the Habaki (blade collar) when fully sheathed.
-
The Result: You can hold the scabbard upside down, and the 47g metal blade will stay securely in place. Yet, with a gentle pull, it releases smoothly for that satisfying shing sound.

Lore Context: The Legacy of Yura
Why does this blade matter? The Nagakiba is the signature tool of Yura, the harsh mentor who warns us about the dangers of Agheel Lake. He is a hunter of his own kind—tracking down those who succumb to the madness of the Bloody Fingers.
In the game, this weapon is often infused with the Bloodflame Blade incantation. The extra reach allows players to apply bleed buildup from a safe distance. While our replica comes in its pristine "steel" state, the zinc alloy surface is compatible with custom painting if you wish to add your own "bloodflame" effects using model acrylics.
Visual Analysis: Beyond the Polygon Count
While other katanas like the Rivers of Blood rely on jagged, organic textures, the Nagakiba is defined by its elegance and length.
If you look closely at our replica, the handle features the distinct teal/dark green wrapping found on Yura's original model. This contrasts sharply with the gold Tsuba (handguard), an oval design that differentiates it from circular guard designs found on other katanas in the game.
The Blacksmith's Verdict
The Nagakiba is a specialized piece. It stands out not just for its lore, but for its physical presence—at 26cm, it dominates any miniature weapon rack. The switch to a hybrid metal-polymer construction was a deliberate engineering choice to ensure the perfect balance between visual fidelity and display stability.
With the new retention upgrade, it is now safer and more satisfying to handle than ever before.
