Care Instruction
  1. Don't cut hard things! Japanese knives are brittle so bone hacking is a NO NO!
  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

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.

    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.

    White Steel #1, also known as Shirogami #1, stands out in the realm of high-end Japanese cutlery materials for its exceptional purity and performance. It is an advanced version of White Steel No.2, achieved through further refinement and an increased carbon content. This additional carbon allows White No.1 to attain a slightly higher hardness (HRc) than its predecessor, enhancing its ability to be sharpened to an extremely fine edge. However, this increase in carbon also introduces a bit more brittleness to the steel. Despite this, White No.1 is highly favored by professional chefs, especially those specializing in traditional Japanese cuisine, due to its superb edge retention and ease of resharpening. Unlike its Blue Steel counterparts, White No.1 lacks chromium and tungsten, focusing instead on achieving the highest possible sharpness. This characteristic, while offering unparalleled sharpness, means it is more reactive and requires careful maintenance, including prompt wiping and drying after use, to prevent corrosion.
