    3. Please don't wash knife with dishwasher, it will damage the wood handle;
    4. Be careful not to leave the knife close to a heat source for a long time;
    5. It is a lot more dangerous to cut with a blunt knife than a sharp knife!
    6. It is best to sharpen a Japanese knife regularly on a waterstone.
    7. Oil the (carbon) knife if storing for an extended period of time to prevent rust.

    • Profile: Sujihiki

      Slicer

      The Sujihiki, also known as Sujibiki, stands out as a Japanese slicing knife, characterized by a thinner and sharper edge than those found in Western kitchens. Its long blade is ideally crafted for the artful, thin carving of cooked meats and for slicing terrines and patés with finesse. Blade lengths span from 210mm to 300mm (8.3 to 12 inches), with 270mm and 300mm being particularly favored for their ability to facilitate smooth and efficient slicing. The meticulous design of the Sujihiki reflects a harmonious blend of traditional Japanese precision and a focused functionality, catering to the needs of culinary professionals and enthusiasts alike.

    • Steel: Blue Super / Aogami Super

      Aogami Super steel, also known as Blue Super Steel, is highly esteemed among Japanese carbon steels for its exceptional qualities. Produced by Hitachi Metals Ltd., this steel surpasses Blue Steel No.1 in its composition, featuring higher amounts of carbon, chromium, and tungsten, with the addition of molybdenum. Aogami Super is celebrated for its remarkable edge sharpness and superior edge retention capabilities. It can achieve high levels of hardness without becoming brittle, a characteristic that sets it apart and endears it to knife enthusiasts worldwide. The steel's enhanced carbon content enables it to maintain sharpness for extended periods, while the added chromium aids in rust resistance. A touch of vanadium increases its toughness, making it less prone to chipping. These attributes make Aogami Super one of the most revered high carbon steels globally, often described as a knife nerd's dream for its balance of hardness, durability, and maintenance ease.

    • Construction: Sanmai - Stainless Clad

      Sanmai(Three-Piece) is a common construction for double bevel knives where two pieces of softer cladding steel are forgewelded to each side of a harder core steel. The harder but more brittle core steel will form the hard cutting edge after heat treating, and the softer cladding will support the core to increase the overall strength of the blade.

      The soft cladding enables the thinning process to be a lot easier than a honyaki or monosteel construction. And in the case where the cladding steel are stainless in nature, it can offer protection for the carbon or semi-stainless cores against rusting and discoluoring.

    • Finish: Tsuchime

      The "Tsuchime" finish in Japanese kitchen knives refers to a distinctive hammered texture on the blade's surface. This traditional technique not only adds a unique aesthetic appeal but also provides practical benefits, such as reducing drag and preventing food from sticking to the blade during slicing. It's a hallmark of craftsmanship that blends functionality with artistry, making each knife not only a tool but a piece of art.
