  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.

Gyuto

Chefs Knife

A Japanese chef's knife is known as a gyuto (牛刀 ぎゅうとう) gyūtō), literally meaning 'beef knife'. Its blade resembles a flatter version of a French chef's knife. Japanese cutlery is known for sharpness due to its acute blade geometry, and the hardness of the steel used, sometimes exceeding 60 HRC on the Rockwell Scale A typical western chef's knife may be sharpened to an edge angle of 20-22°, while a Japanese gyuto generally has a sharper edge angle of 15-18° (or even lower), which requires a harder, more brittle grade of steel. In recent years Japanese gyuto have gained in popularity with western chefs.

A modern chef's knife is a multi-purpose knife designed to perform well at many differing kitchen tasks, rather than excelling at any one in particular. It can be used for mincing, slicing, and chopping vegetables, slicing meat, and disjointing large cuts.

SG2 / R2 Element Composition

Compare with
    SG2 / R2
    14.0% 10.5% 7.0% 3.5% 0
    C Carbon 1.25%
    Primary hardening element. Raises hardness and wear resistance — but too much increases brittleness and corrosion susceptibility. As a reference: German 1.4112 (~0.5%) sits at the low end; VG-10 (~1.0%) is a common mid-range; SG2 (1.25–1.45%) and ZDP-189 (~3.0%) represent high and extreme ends respectively.
    C
    1.25%
    Cr Chromium 14.0%
    Raises corrosion resistance; 13%+ qualifies steel as stainless. Also improves hardenability and wear resistance. In kitchen use, higher chromium levels contribute to a slight drag or sticking sensation when cutting — a trade-off for the rust resistance it provides.

    Forms extremely hard carbides for superior edge retention. Also refines grain structure, improving toughness.

    SG2, also known as Super Gold 2 or R2 steel, is a high-end powdered tool steel by Takefu Special Steel, known for its excellent edge retention, wear resistance, and ability to achieve a hardness of up to 64 HRC. Identical to Kobelco Steel's R2, it's prized in premium knife making for its fine edge sharpness and durability. The powdered nature ensures uniform carbide distribution, enhancing toughness and reducing chipping risks. SG2/R2 is ideal for those seeking top performance and longevity in their cutting tools.
    Construction: Sanmai - Stainless Clad
    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
    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.
