This knife is like a mix between a petty knife and a true all-rounder bunka knife. With its 150mm blade length, it's perfect for most kitchen tasks. You can use it for cleaning, peeling, and prepping veggies without feeling limited by its size. And when it comes to chopping, it delivers flawless performance. The pointed k-tip allows for precise control and maneuverability, enabling you to navigate tight corners or perform detailed cuts.
Shirogami #2 is a traditional high-carbon steel. Due to its high carbon content, it can reach a hardness of over 60 HRC, which means that blades forged from it will have excellent edge retention. It is renowned for its exceptional sharpness, durability, and ability to hold a keen edge.
Just keep in mind that this blade is a bit more delicate. So, make sure to follow some basic care and maintenance tips for Japanese knives when you're using it. Taking good care of it will keep it in top shape for a long time. → Read more about how to take care of high carbon knives and patina in our Knife maintenance blog post.
It's important to note that Shirogami steel requires proper care and maintenance to prevent rust and maintain its performance.
The steel will gradually acquire a patina, which only endows this knife with more charm. Do not wash this knife in a dishwasher, but rather wash it by hand and wipe it with a dry cloth. The advantage of having a blade made of high carbon steel is the fine sharpness, ease of sharpening, and long edge retention. We recommend the occasional coat of knife maintenance oil to protect the blade from external influences.
The blade was laminated with soft iron, which is iron with only a small amount of carbon added to it. Laminating the blade improves its structural integrity, as the knife’s core is made of hard—and therefore brittle—high-carbon Aogami #2 steel that is prone to breakage on its own.
Due to its purity and lack of any added elements such as chromium (Cr), soft iron doesn’t resist corrosion well. Therefore, the upper laminated part can also develop rust when not taken care of properly.
It has a double bevel (symmetrical) blade.
Viewed from the back of the blade, the knife is heavier and stronger at the handle and thinner and more precise at the tip. This blade shape makes the knife easier to use because the blade is very responsive, easily maneuverable and nicely balanced. This type of blade design is also called distal taper - you can read more about it in the article on blade geometry.
The knife has a kuro-uchi finish, which gives it a unique, rustic look. It's worth noting that each blade in the series is individually handcrafted. You might notice some minor imperfections or scratches. However, these are just signs of the hand-making process and do not affect the overall quality of the knife. Oh, and there's also the master's signature engraved in Kanji characters on the blade. Pretty cool, right?
The handle is octagonal and made from a single piece of oak wood. It fits perfectly in both left and right hands. People are starting to prefer oak handles over the traditional magnolia ones in their home kitchens because they're sturdier and can handle all sorts of wear and tear. Plus, they just look really nice!
Tsukasa Tokaji is an exceptionally skilled blacksmith from the Japanese city of Kōchi. He dedicated himself to the art of knife making under the mentorship of renowned blacksmith Tadayoshi Tokaji, mastering traditional techniques of free forging over the years. Tsukasa's knives are crafted from Shirogami carbon steel and laminated with soft iron. This combination ensures outstanding durability and blade strength, making the knives reliable and suitable for long-term use.

☝️ THIS KNIFE MAY DEVELOP PATINA
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).

GENERAL KNIFE CARE TIPS:
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.
