Sukenari ZDP-189 Gyuto 210mm with Ebony Buffalo Horn Handle

by Sukenari


Many knife enthusiasts have Sukenari ZDP-189 in their wishlists, but the top range ZDP-189 is often quite expensive. Beautifully hand-grinded and extremely thin behind the edge, the cutting performance of this knife is simply sensational. We have decided to add this ZDP-189 Gyuto with a simple polished finish, which brings down the cost but not the cutting performance. By removing finishes that do not contribute to knife performance, this Sukenari Gyuto is both affordable and extremely high performing. Production is extremely limited, and wait time is on average one year once sold out.

    About ZDP-189 Steel

    ZDP-189 is a super steel from Hitachi, with extremely high carbon and chromium content. The steel can achieve superbly high hardness, enabling some artisans to harden the knife to up to 67HRC. ZDP-189 knives are pricier compared with knives of same style and finish but with a lesser steel. These knives could retain sharpness much longer, but require more experience when it comes to sharpening. Burrfection Store does not recommend sharpening beginners to buy this knife as their first knife.

    Wash and dry with a soft sponge, and safely store after use. Avoid cutting into bones, frozen foods, hard fruit pits.

    Cutting Surface:

    Recommended cutting surface: wood, rubberized boards, and high-end composites, and quality plastics such as polyethylene make acceptable cutting surfaces, and will help protect and prolong the knife’s edge. AVOID glass, metal, countertops, and other rigid, non-forgiving surfaces.


    We recommend sharpening all quality Japanese knives on whetstones, as we believe they yield the best results for your knives.
