Kuroki Katana Specifications

Damascus Steel with Genuine Hamon

The blade combines two advanced forging techniques. The Damascus steel is folded from multiple layers, acid-etched to reveal the internal grain — organic lines flowing across the polished surface. Over that Damascus pattern, a genuine hamon (notare — gentle undulating waves) runs the blade's length, the boundary between hard martensite edge and softer pearlite spine clearly visible. Creating a hamon on Damascus is harder than on single-steel: the layered composition responds unpredictably to differential quenching, and the smith must control both the fold pattern and the hardening simultaneously. The Kuroki katana delivers both without either feature compromising the other. If you want to understand how katana forging works at this level, our article walks through every step.

Magnolia Wood Saya — Shirasaya Tradition

The saya is magnolia wood (honoki) — the same timber used for traditional Japanese shirasaya (storage scabbards) for centuries. The grain is left fully visible: warm honey-beige tones with natural markings, no lacquer, no paint. Magnolia is specifically chosen because it does not react with blade steel, absorbs moisture evenly, and splits cleanly along the grain for precise fitting. On the Kuroki katana, the unfinished saya is the design statement: this is a blade that presents its materials honestly, without cosmetic processing.

Stingray Leather Ito & Genuine Rayskin

The handle wraps in genuine stingray leather ito — not cotton, not silk, not PU leather. Stingray has a distinctive fine-grain texture, darker and more uniform than cotton cord, and ages into a burnished surface through handling. Beneath the ito, genuine white rayskin (samegawa) provides the nodular grip foundation. The Kuroki katana is the only blade in our catalog using stingray leather wrapping — it is the premium alternative for collectors who want traditional materials at every contact point.

Copper Serpent Tsuba

The copper tsuba features a three-dimensional serpent coiled across the guard face — sculpted in relief, not flat engraving. The serpent wraps through and around the disc, its body projecting from the surface. Copper is warmer and heavier than iron, and develops a dark patina over time that matches the aged tone of the magnolia saya. The brass habaki carries the openwork crackle pattern seen across our premium Damascus lineup. Every metal fitting on the Kuroki is a different alloy — copper tsuba, brass habaki — each selected for its properties rather than matched for uniformity.

Display

Ships with a simple black modern stand. The natural magnolia saya and Damascus blade create a palette that reads as authentic artisan work rather than decorated merchandise. The Kuroki pairs with our Wooden Katana and Yamitsuki for a natural-materials display, or stands alone where the Damascus grain and magnolia grain create a conversation about raw materials meeting refined technique. If you're looking for a real katana where every component is genuine, this is it.

Frequently Asked Questions

What does Kuroki mean?

Kuroki (黒木) means "black wood" or "unprocessed timber" — lumber left in its natural state without artificial coloring. In Japanese architecture, kuroki is used in sacred Shinto shrine construction. The name reflects this katana's philosophy: authentic materials honestly presented.

What is the ito made of?

The ito (handle wrapping) is genuine stingray leather — not cotton, silk, or synthetic PU leather. Stingray has a distinctive fine-grain texture and develops a burnished surface through handling over time.

Is this Kuroki katana sharp?

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

Why is the saya unfinished?

The magnolia wood saya is left with its natural grain visible — no lacquer, no paint. This follows the shirasaya tradition of presenting wood in its authentic state. Magnolia is the traditional material for Japanese sword storage scabbards because it does not react with blade steel.

Does the blade have both Damascus and hamon?

Yes. The blade shows both a Damascus fold pattern (visible grain from layered steel) and a genuine hamon temper line (notare pattern). Achieving both on a single blade is technically demanding because the folded steel responds unpredictably to differential hardening.
