Miyabi Koh 4000FC Knives

The Precision of a Scalpel, the Soul of a Samurai Elevate your culinary artistry with the Miyabi Koh 9.5-inch (240mm) Slicer, a tool specifically designed for the chef who demands surgical precision. Known in Japan as a Sujihiki, this knife is the long, thin-bladed alternative to the Western carving knife. Whether you are portioning a delicate tuna loin for sashimi or carving a prime rib roast, the extended 240mm length allows for long, continuous drawing cuts. This single-motion technique prevents the 'sawing' motion that tears delicate proteins, ensuring clean surfaces that lock in juices and preserve texture. Advanced Metallurgy Meets Traditional Craft At the heart of this blade is the revolutionary FC61 Fine Carbide Stainless Steel. This advanced alloy bridges the gap between two worlds: it offers the legendary edge retention of high-carbon Japanese steel while maintaining the robust toughness and corrosion resistance typically found in high-end German cutlery. With a 61 Rockwell Hardness, the edge is exceptionally durable, yet remains approachable for sharpening. Each blade undergoes the proprietary FRIODURx2 ice-hardening process, a specialized thermal treatment that optimizes the molecular structure of the steel for maximum sharpness and flexibility. Handcrafted Excellence from Seki, Japan Every Miyabi Koh knife is handcrafted in Seki, the historical capital of Japanese sword-making. Artisans employ the Honbazuke three-step honing process, hand-finishing each edge to a staggering 9.5 to 12-degree angle. This results in a 'katana' edge—a mirror-polished tribute to the samurai swords of old. The aesthetic is completed by a sandblasted katana edge and an embossed MIYABI logo, signifying a product that is as much a work of art as it is a professional tool. Learn More
