Sakai Takayuki / Itsuo Doi "Homura Guren" Aogami #2 Kurouchi Tsuchime 150mm Petty

by Sakai Takayuki


The "Homura Guren" knives are handcrafted by Sakai master blacksmith Itsuo Doi. Using Aogami #2 as core steel, clad in soft iron, the blade was heat-treated to 62-63 HRC for superb edge retention. The beautiful distal tapering and edge geometry ensure a superb cutting performance, and the Kurouchi Tsuchime finish gives this knife a characterful accent. The wa-handle is made of burnt Japanese Oak wood, coated with Urushi. Every knife is engraved with personal seal of Itsuo Doi.

Aogami #2 (Blue #2) steel is a premium Japanese high carbon steel for knife making. It is not stainless, therefore you must wipe your knife dry after each use, in particular the core steel not covered by the stainless cladding. Patina will develop over time, which will appear as “discoloration” on the cutting edge, but that is the nature of carbon steel - not a defect. The stainless cladding covers a large part of the blade, making maintenance easier but still preserving the cutting and sharpening pleasure of the Aogami #2 core. Avoid cutting into bones, frozen foods, hard fruit pits.

Cutting Surface:

Recommended cutting surface: wood, rubberized boards and high-end composites, and quality plastics such as polyethene make acceptable cutting surfaces, and will help protect and prolong knife’s edge. AVOID glass, metal, countertops, and other rigid, non-forgiving surfaces.


We recommend sharpening all quality Japanese knives on whetstones, as we believe they yield the best results for your knives.
