    Another addition to the ever popular Hatsukokoro Hayabusa(隼,Peregrine Falcon) line, featuring the edge retnetion king: Hitachi ZDP-189 powdered steel. With over 3% of carbon content and up HRC 67, the Hayabusa ZDP-189 line is designed for those seeking the ultimate long lasting edge.

    Previously this steel was almost found exclusively on Sukenari knives, and they usually comes with a rather big price tag. That situations may just change with the introduction of the Hayabuse ZDP-189 serie, with a fit and finish that is arguably on par with the Sukenari, these hyper steel blades comes in with a price that is close to some SG2 knives. Hayabusa also offers a very thin grind, as a result it is a lightweight laser, with a thin flexible blade.

    For those who are fascinated by the knives with cutting edge(pun intended) powder metallurgy and extreme numbers, this undoubtedly will be the easiest way to get your hands on the ZDP-189 steel.

    Pros Cons
  • Budget friendly
  • Great for professionals
  • Excellent performance
  • Relatively hard to sharpen
  • Fit and finish can be improved

  • 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.


    An emerging brand rapidly building up its reputation internationally, Hastukokoro offers a great selections of premium hand crafted knives sourced from makers all over Japan. Top tier knife makers such as Yoshikane, Nigara and Nakagawa Hamono all send their best knives to Hyogo.

    • Profile: Santoku

      The Santoku knife, embodying the meaning "three uses," is a cornerstone in Japanese kitchens, adept at slicing, dicing, and mincing. Esteemed for its versatility, it features a blade length typically between 15cm and 20cm (6 to 8 inches), catering to a wide array of culinary tasks. Distinguished by its less pointy tip compared to the Gyuto, the Santoku boasts a unique profile that contributes to its functionality and popularity. Its design is tailored to provide ease and efficiency in preparation, also because of its less aggressive prrofile, making it a preferred choice for home cooks.

    • 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 Damascus 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.

      Damascus Sanmai utilize damascus steel as the cladding material for the Sanmai construction, which adds aesthetic feature to the blade. On the Kitchen knives with stainless core steel, the damascus cladding will be stainless, this means they will also protect the carbon/semi-stainless core from rusting/discolouration.

      The soft cladding enables the thinning process to be a lot easier than a honyaki or monosteel construction. However, when the cladding is made of damascus, whether etched, polished or mirror polished, the thinning process will take a toll on the cladding, meaning the damascus won't look the same as when it was taken out of the box.

    • 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.
