    Care Instruction

    2. Wash with neutral detergent after use, and wipe dry;
    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: White 2 / Shirogami #2

      White Steel No.2, also known as Shirogami #2 or White Paper #2, is long regarded as the go-to choice for crafting high-grade Japanese kitchen knives. This steel is celebrated for its capacity to be fashioned into knives that exhibit a sharp cutting edge, moderate tenacity, and long-lasting sharpness, alongside being notably easy to sharpen. While it possesses a slightly lower carbon content (C: 1%) compared to White Steel No.1 (C: 1.3%), it still requires a high level of craftsmanship to manipulate effectively. The expertise of a skilled blacksmith is crucial in transforming this material into a premium quality kitchen knife. Despite its excellent qualities, White Steel No.2 is known to be very reactive; hence, knives made from this steel demand meticulous care, including immediate wiping and drying after use, to prevent corrosion.

      Sanjo and Sakai are known to widely utilise Shirogami #2 in their mainstream kitchen knives.

    • Construction: Monosteel

      A "monosteel" construction in the context of Japanese kitchen knives refers to knives that are made from a single type of steel. Unlike traditional Japanese knives that might use a layered steel construction (like "san mai," which sandwiches a hard core steel between softer steel layers), monosteel knives are crafted from a single piece of steel throughout the blade. This type of construction can offer a balance of durability, ease of sharpening, and maintenance.

      Monosteel knives are appreciated for their uniformity in material properties across the blade, providing a consistent cutting experience. This also means the characteristics of the steel will be applied to the whole blade, if a monosteel blade is made of carbon steel, the entire surface of the blade will require maintenance to prevent rust and discolouration. This too, applies to the hardness, an uniformly hardened blade can be difficult to manufacture, and can be quite difficult for uers to perform thinning.

      It should be noted that monosteel knives are usually not forged, as the forged knives, along with differential heat treatment line is called Honyaki.

    • Finish: Migaki

      "Migaki" means "polished" or "shined" in Japanese, The term "Migaki finish" in the context of Japanese kitchen knives indeed does not exclusively refer to a mirror polish but encompasses a broader range of polished finishes that can vary from semi-gloss to a more refined, subtle sheen, rather than a highly reflective surface. The primary goal of a Migaki finish is to enhance the knife's functionality and aesthetic appeal, focusing on a smooth finish that improves resistance to corrosion and minimizes drag during cutting, rather than achieving a purely mirror-like appearance.
