Maguro Kiri Kasumi Shirogami 540mm (21.3")
Maguro Kiri Kasumi White Steel 540 is a large knife designed for cutting tuna. It is a hybrid between Deba and Yanagiba and allows the user to cut large fillets in a single slicing motion. On one hand, the knife is extremely precise and doesn’t damage the delicate tissue of raw meat, on the other, it is robust enough to cut such large fish.
The single-bevel blade (for right-handed users only!) is 540 mm long and comes complete with a wooden protective Saya. The knife has a wonderful finish as it is ground and polished on natural whetstones. A pronounced wavy line, called the Kasumi (mist) finish, flows along the cutting edge.
With knives requiring long-term sharpness, high-carbon steel is usually chosen, which is why this giant is also made from extremely pure White Steel 2. It has no additives (it may contain some phosphorus and sulfur as an impurity though). Because this steel has a lower percentage of Chrome, the blade gets some patina after some time, but the pluses outweigh the minuses. It has a very fine, gentle sharpness, is easy to resharpen, and will remain sharp for a long, long time.
The good-size handle is made of magnolia wood and is finished with a buffalo horn ferrule. The size and shape of the handle enable a comfortable grip and safe work.
The knife is made in the famous knife capital Sakai.

☝️ Japanese kitchen knives in our store are handmade from natural materials. Slight variations in color, texture, weight and other dimensions are possible.

☝️ 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.
✔ Use a magnetic rack, knife blocks, or use 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.
❗️A knife is a tool intended for specific use: it’s not a can opener, screwdriver, trowel, wire cutter, hammer etc. Kitchen knives are meant for preparing food.
