Miyabi Birchwood 9-inch Chef Knife

The Apex of Japanese Metallurgy and Natural Artistry

Master large-scale prep with a 240mm SG2 micro-carbide core blade, ice-hardened to 63 Rockwell for a scalpel edge that defies traditional sharpening intervals.

The Miyabi Birchwood 9-inch (240mm) Chef Knife is not merely a tool; it is a high-performance instrument designed for those who demand more than a standard 8-inch blade can provide. Handcrafted in Seki, Japan, this knife utilizes an SG2 micro-carbide powder steel core, a material renowned in professional circles for its ability to hold a 9.5° to 12° Honbazuke edge through hours of heavy prep work without rolling.

The 240mm length offers a distinct advantage for high-volume kitchen environments. Whether you are slicing through massive heads of cabbage or breaking down large proteins, the extra inch of blade travel reduces fatigue by requiring fewer strokes. The blade is protected by 101 layers of stunning flower Damascus, while the CRYODUR ice-hardening process ensures the molecular structure remains stable at a staggering 63 Rockwell hardness.

Completing the aesthetic and functional profile is the Karelian (Masur) Birch handle. This rare wood—the only timber ever featured in a Fabergé egg—is exceptionally dense and resistant to the moisture of a busy kitchen. Its ergonomic D-shape provides the tactile feedback necessary for precision dicing, making it a favorite for hybrid users who transition from delicate herb work to heavy vegetable chopping.
