Shirasagi Tsuchime Sakimaru Yanagi 300mm is a traditional Japanese knife used for preparing raw fish, especially for sashimi and nigiri sushi. Its length allows the user to slice the fish in one single pulling motion, that will – together with the razor-sharp single bevel blade – birth smooth, shiny cuts. The name sakimaru refers to the tanto tip, which is, besides looking awesome, also an homage to the katana.

Traditional Japanese knives are made from steels high in carbon content, and this is mainly for two reasons:

  • due to the steels’ pure composition, the blades are able to achieve an extremely fine sharpness,
  • for the same reason, once they get dull, they can be easily resharpened back to optimal shape.

Aogami #2 is one of the best in the high-carbon class, with added elements such as chromium (Cr) and tungsten (W) for improved corrosion and wear resistance, all while having an awesomely fine sharpness and being able to get resharpened easily.

Yanagiba (literally ‘willow’, as its shape is reminiscent of a willow leaf) is one of the three traditional Japanese knives (others being deba and usuba), and it’s used for slicing raw fish. They have a single bevel, which can achieve a much finer sharpness – this is key if you want the cut to be as clean and smooth as possible. Yanagiba knives are usually 240-360 mm long, which allows the user to slice the sashimi in a single pulling motion to prevent any shredded, zigzag cuts that would result in damaged food tissue.

Aogami #2 is a very popular steel in Japanese knifemaking and one of the finest high-carbon steels, meaning the knives forged from it will have excellent edge retention and also sharpen very easily. At the same time, it is less resistant to corrosion, meaning the blade can develop a patina, while longer exposure to water or other corrosives could also lead to rusting. This is improved to some extent with the addition of chromium and tungsten, but it’s still a high-carbon steel that should be maintained accordingly (⚠️ read more about knife maintenance here). Aogami #2 steel is composed of carbon (C) 1.1 %, chromium (Cr) 0.5 %, manganese (Mn) 0.3%, and tungsten (W) 1.5%.

Ni-mai lamination method is used on single-bevel knives, where a sheet of softer metal is forge-welded onto the shinogi (front) side of the blade’s hard core. This reinforces the blade’s structural integrity and consequently makes it tougher.

It has a single bevel blade.

The upper part was left untreated – we call this a kuro-uchi finish (kuro - ‘black’), which is a layer of raw, protective patina on the outer steel. It gets a nice contrast from the kanji that bears the name of the smithy, Hatsukokoro (初心). The kireha (lower part of the blade or ‘blade road’) has a classic cloudy kasumi finish.

Japanese (Wa) style handle made out of wenge wood with a buffalo horn ferrule.

☝️ Japanese kitchen knives in our store are handmade from natural materials. Slight variations in color, texture, weight and other dimensions are possible. We try to give a good photographic representation of our products, however computer screen resolution and colors do vary, so products might not look exactly as they are seen on screen.


Knives made of carbon steels can, due to their low chromium (Cr) content, discolor and develop patina. The knife is the most sensitive when it is still new and a patina had not developed yet, but later, patina will protect the blade. These types of knives require a touch more care:

✔ Wipe it regularly with a clean and dry cloth (you can also do this during use).
✔ After use, rinse it with lukewarm water and wipe it dry.
✔ Coat it regularly with knife maintenance oil or plain refined sunflower oil.
✔ Store the knife by wrapping it in paper which will absorb moisture and protect the blade.

A patina is a thin layer that forms on the surface of oxidized steel and protects it from further oxidation. The patina should not be confused with rust. Patina protects the blade, while rust causes corrosion and deterioration of material, so it should be removed (see Rust erasers).

→ For in-depth information about patina, read our dedicated post on patina.


Blade wear depends on the quality of steel, usage and maintenance of the blade. Japanese knives are made of high-quality steels. Follow these tips to keep your Japanese knife in top-notch shape:

✔ Use a wooden, plastic or rubber cutting board.
✔ After use, wash the knives and wipe them dry.
✔ For storage, use a knife holder or a protective knife sheath (saya).
✔ A good cutting technique is your best bet to prolong sharpness.
✔ Use sharpening stones to sharpen the knife.

❗️Don’t leave the knife in the sink. Wash it by hand.
❗️Don’t wash the knife in the dishwasher.
❗️Don’t use the knife on glass, ceramics, marble or steel surfaces.
❗️Don’t scrape the food off the cutting board with the edge of the blade. Use the spine of the knife instead.
❗️Knife is a tool intended for specific use - cutting food. It is not a can opener, screwdriver, trowel, wire cutter, hammer etc.
