Sakai Takayuki / Itsuo Doi "Genbu" Aogami #2 Mirror-Finish 300mm Sakimaru Takohiki with Ebony Buffalo Handle and Kuroishime Saya

by Sakai Takayuki


Sakai Takayuki’s “Genbu” Takohiki is handcrafted by the renowned Sakai blacksmith Itsuo Doi, son of legendary blacksmith Keijiro Doi. Itsuo Doi is a master of single bevel traditional Japanese knive. This Takayuki "Genbu" is a great example of Doi's extraordinary hand forging, welding and grinding works. The knife is finished by hand mirror polish and a refined hon-kasumi on the grind. Inspired by traditional Japanese katanas, the sakimaru takohiki has a wider blade than most other sushi/sashimi knives. This sakimaru tokohiki comes with a black Kuroishime saya.

Aogami #2 (Blue #2) steel is a premium Japanese high carbon steel for knife making. Despite some corrosion resistant quality (for a carbon steel), it is not stainless, therefore you should wipe your knife dry after each use. Patina will develop over time. Rust may develop if left in prolonged contact with water or acidic food. Use a rust eraser to clean if rusts develop. 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.
