The Kouki Blue #2 Kurouchi Gyuto 150mm is a compact chef’s knife that delivers precision, agility, and impressive cutting performance in a small package. Forged from Aogami (Blue #2) carbon steel, it offers excellent edge retention, a keen edge, and straightforward sharpening. The kurouchi finish adds a rustic, traditional character while helping protect the blade from corrosion.

Crafted by Takahiro Hashimoto, a second-generation smith from the Tosa Forged Blades School (Kajiya Soseijuku), this knife reflects both heritage and youthful mastery. After serving as an instructor, he launched his own workshop in April 2025 at just 27. “Kouki” (光貴) combines characters from his and his father’s names, symbolizing legacy and craftsmanship.

Ideal for precise prep work with exceptional control.

Profile: Gyuto

Chefs Knife
A Japanese chef's knife is known as a gyuto (牛刀ぎゅうとう） gyūtō), literally meaning 'beef knife'. Its blade resembles a flatter version of a French chef's knife. Japanese cutlery is known for sharpness due to its acute blade geometry, and the hardness of the steel used, sometimes exceeding 60 HRC on the Rockwell Scale A typical western chef's knife may be sharpened to an edge angle of 20-22°, while a Japanese gyuto generally has a sharper edge angle of 15-18° (or even lower), which requires a harder, more brittle grade of steel. In recent years Japanese gyuto have gained in popularity with western chefs.

A modern chef's knife is a multi-purpose knife designed to perform well at many differing kitchen tasks, rather than excelling at any one in particular. It can be used for mincing, slicing, and chopping vegetables, slicing meat, and disjointing large cuts.

Steel: Blue 2 / Aogami #2
Blue Steel No.2, also recognized as Aogami No.2, is a distinguished high carbon steel produced by Hitachi Metals Ltd, enhanced by the addition of chromium and tungsten to the base of White Steel No.2. This modification brings about an improvement in toughness and the creation of hard carbide molecules, which significantly boost edge retention. Although its sharpness is comparable to that of White Steel No.2, Blue Steel No.2 offers a slight advantage in maintaining its edge.

Widely favored for its versatility, Aogami No.2 is celebrated for its ease of sharpening and robust resistance to chipping, making it an ideal choice for those new to Aogami steel knives. Containing 1.0–1.2% carbon and achieving a typical hardness of 62–63 HRC on the Rockwell scale, it stands as the benchmark in evaluating Aogami steel cutlery.
