    Pros Cons
  • Excellent performance
  • Great for professionals
  • Relatively hard to sharpen

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


    Sukenari(佑成), a brand with a trademark written in two Kanji, one is "to support" or can be broken down to "human and its right side", the other one is "become, achieve). According to the current Representative Director Nobuo Hanaki, this name is filled with the desire of making product that will become an inseparable part in the right hand of those who cook.

    Eversince the founding of the company in Showa 8th(1933), Sukenari have been renowned for its products utilizing the hardest manufacturing technique of Honyaki. This applies not only to the traditional carbon steel, but also to modern stainless alloy steels, or even powder metallurgy steels. It is quite safe to say Sukenari, is one of the most, if not the most pioneering Japanese company in terms of new steel selection, with glorious track records of forging with steels never seen on any other kitchen knives.

    • 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.

    • Steel: ZDP-189

      ZDP-189 steel is a high-end powdered metallurgy stainless steel renowned for its exceptional hardness and edge retention capabilities. Developed by Hitachi Metals, it contains a high carbon and chromium content, allowing it to achieve hardness levels up to 67 HRC, making it one of the hardest steels used in knife making. This extraordinary hardness means that ZDP-189 can be sharpened to a very fine edge and maintain that sharpness through extensive use, far surpassing many other steel types in terms of edge retention. However, its high hardness also means that it can be more challenging to sharpen and may be more prone to chipping if used improperly. ZDP-189's significant chromium content also provides it with a degree of corrosion resistance, though care should still be taken to maintain the blade. Due to its premium qualities, ZDP-189 is often used in high-end and specialty knives, appealing to enthusiasts and professionals who prioritize cutting performance and longevity.

    • 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: 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.
