Motokane Tosa Funayuki 165mm Aogami No. 1 Kurouchi

Product description

This Funayuki knife is hand-forged by Master Motokane from the Tosa region (Kochi Prefecture, Japan), which is known for its long tradition of making authentic "honmamon" blades — true handmade knives with the soul of Japanese blacksmithing.

The blade is forged from Aogami No. 1 (Blue Paper Steel) with a core of soft iron , creating a blade with an excellent combination of sharpness, toughness and easy resharpening. The black-forged (kurouchi) finish protects the blade from corrosion and gives it a traditional, rustic look.

Each knife is an original – hand-shaped, with a precisely aligned edge and elegant blade line. Even when using the same materials and methods, the details may vary slightly during hand-making – this is what makes each piece a unique artisan original.

Originally, this type of knife was used by fishermen on boats (Funayuki = "boat knife") to prepare fresh fish, but thanks to its universal design, it is now also ideal for cutting vegetables, meat and preparing sashimi.

Recommendations for new knives

The blade is coated with a protective varnish against corrosion - we recommend first use after resharpening to restore the original sharpness.
To achieve maximum performance, we recommend that you gently sharpen the knife on a water stone before using it for the first time.
We offer knife sharpening - we will be happy to recommend a suitable stone or service depending on your style of use.

Knife maintenance recommendations

After use, rinse the knife, dry it and store it in a dry place.
Regular fine grinding will extend the life of the blade and maintain optimal cutting performance.
Carbon steel can develop a patina over time, which is a natural and desirable phenomenon.

Warning – carbon steel knives

Aogami No. 1 carbon steel requires basic maintenance, but will reward you with exceptional sharpness and long life.
Proper care will ensure a long life and consistent performance of the blade.

Notice

Not suitable for dishwashers or dishwasher dryers - high temperatures and chemicals can damage the blade and handle.
The knife is not intended for cutting bones, frozen foods or extremely hard ingredients.
Each piece is an original – minor irregularities, scratches or loose parts of the oxide coating are not defects, but evidence of the traditional manual process.
