Master Shibata Takayuki’s Koutetsu line embodies his motto: "Art Over Beauty." These ultra-thin lasers glide effortlessly through food, resisting stickage with their hazy, textured finish. Every blade is hand-ground and sharpened by Shibata himself—ensuring insane sharpness and flawless geometry.

Forged in Takefu with a Bunka-style angled tip, the design pays homage to Japan’s historic Koutetsu warship—built for speed and power. Yet these knives are featherlight and agile, with a comfortably rounded spine and choil for marathon prep sessions.

Shibata’s obsession with performance shines: no-nonsense sharpness, food-release texture, and hand-signed precision. This isn’t just a knife—it’s a cutting masterpiece.

For those who prioritize performance over polish, the Koutetsu delivers: razor-sharp, comfortable, and engineered to excel.

Care Instruction

Don't cut hard things! Japanese knives are brittle so bone hacking is a NO NO!
Wash with neutral detergent after use, and wipe dry;
Please don't wash knife with dishwasher, it will damage the wood handle;
Be careful not to leave the knife close to a heat source for a long time;
It is a lot more dangerous to cut with a blunt knife than a sharp knife!
It is best to sharpen a Japanese knife regularly on a waterstone.

鋼材： SG2 / R2
SG2, also known as Super Gold 2 or R2 steel, is a high-end powdered tool steel by Takefu Special Steel, known for its excellent edge retention, wear resistance, and ability to achieve a hardness of up to 64 HRC. Identical to Kobelco Steel's R2, it's prized in premium knife making for its fine edge sharpness and durability. The powdered nature ensures uniform carbide distribution, enhancing toughness and reducing chipping risks. SG2/R2 is ideal for those seeking top performance and longevity in their cutting tools.

建構：三枚 - 不鏽鋼夾層

Sanmai(Three-Piece) is a common construction for double bevel knives where two pieces of softer cladding steel are forgewelded to each side of a harder core steel. The harder but more brittle core steel will form the hard cutting edge after heat treating, and the softer cladding will support the core to increase the overall strength of the blade.
The soft cladding enables the thinning process to be a lot easier than a honyaki or monosteel construction. And in the case where the cladding steel are stainless in nature, it can offer protection for the carbon or semi-stainless cores against rusting and discoluoring.

完成： Migaki

「Migaki」在日文中意指「拋光」或「磨亮」。在日本廚刀領域，「Migaki仕上」並不專指鏡面拋光，而是泛指從半光澤到細膩柔和光澤的各種拋光處理，而非極度反光的表面。Migaki拋光的主要目的是提升刀具的功能性與美觀，重點在於打造光滑表面以增強抗腐蝕性並減少切割時的阻力，而不是單純追求鏡面效果。

手柄規格
個人資料：八角和柄

材料：
- 紫檀木
An octagonal rosewood handle with a black ferrule is a classic choice for traditional Japanese kitchen knives, combining elegance, comfort, and durability.
The octagonal shape offers a secure, ergonomic grip suitable for both right- and left-handed users, allowing precise control during delicate cuts.
Rosewood, prized for its rich reddish-brown hue and fine grain, adds warmth and a refined aesthetic to the knife, while also resisting wear and moisture over time. The black ferrule, typically made from buffalo horn or durable synthetic materials, reinforces the junction between blade and handle, providing structural stability and a smooth transition for the fingers.
This combination of natural wood and contrasting dark ferrule not only enhances visual appeal but also reflects the craftsmanship and tradition behind Japanese knife-making. Lightweight yet sturdy, the design ensures extended comfort for professional and home chefs alike, making it a functional and timeless handle style.
