Powder steel knives are next level and we have something limited and rare on deck. Introducing the HAP-40 Wide Gyuto Black Ebony 240mm (9.5") [limited]. This limited edition Wide Gyuto is made from premium powder steel, HAP-40, and features a traditional octagonal ebony wood handle. Limited stock—only 30 available!
HAP-40 Wide Gyuto Black Ebony 240mm (9.5") [limited] is our second all-rounder made of powder steel that we designed in collaboration with the Japanese master blacksmith Osamu-san from the Yoshida Hamono smithy. With the HAP-40 series, we fused an optimal blade shape that matches the versatile nature of Western cuisine, Japanese tradition and knowledge of blade design and materials processing.
HAP-40 Wide Gyuto Black embodies the best characteristics we could possibly expect from a kitchen knife:
|
BLADE SHAPE:
Gyuto is the Japanese version of the classic Western Chef’s knife. Wide Gyuto, however, has a little twist to its shape: with a pronounced curved belly and a very wide blade, it sets itself apart from traditional Japanese blades and is suited to Western cutting and chopping techniques. The standard gyuto shape thus transforms into a blade that looks like a deba but is readily used for precision cutting, where you need really thin cuts (this makes it unsuitable for cutting through bones or making more robust cuts). A slight belly curve makes it great for rocking cutting technique, while the pronounced tip, triangular design and an enviable length (240mm / 9.5") will make quick work of larger chunks of meat.
HANDLE:
HAP-40 line features the most traditional Japanese wooden handle (Wa) there is - magnolia wood with buffalo horn ferrule. A universal, octagonal shape comfortably fits in the hands of both right- and left-hand users.
STEEL:
The secret of this knife lies in extremely (68 HRC!) hard core made of a somewhat exotic and currently one of the most mysterious and attractive steels produced in Japan (at least as far as kitchen knives are concerned): Hitachi’s HAP-40 steel that fits into the category of modern and technologically advanced steels. HAP-40 is fine-grained enough to sharpen very well, and knives from this steel keep their sharpness 3-5 times longer than traditional knives. An interesting fact is that, considering it is a powder steel, it has an extremely small content of chromium (around 4%) and can react as a high-carbon steel in specific circumstances.
This steel is heat-treated to an incredible 68 HRC, yet it can still be relatively easily sharpened on whetstones.
COMPOSITION: 1.27–1.37% carbon (C), 3.70–4.70% chromium (Cr), 5.60–6.40% tungsten (W), 4.60–5.40% molybdenum (Mo), 2.80–3.30% vanadium (V) and 7.50–8.50% cobalt (Co). |
LAMINATION:
Blacksmiths counter the brittleness of material with special composition of the knife. In the case of this HAP-40 Wide Gyuto, Osamu-san chose a san-mai (also called “sandwich”) method. A layer of the core steel (HAP-40) is laminated between two external layers of softer, stainless steel. This creates a highly durable kitchen knife with a slightly more pliable core. The main advantage of these knives is that they are thin, sharp and retain their edge very well.
GEOMETRY:
It has a double bevel (symmetrical) blade.
BLADE FINISH:
The blade has a dark finish which is the reason why this look is also called kuro-uchi - the word “kuro” means black. This look is traditional and robust, with an unprocessed top part of the blade that has already developed a dark patina.
Chef and entrepreneur J. Hartley had this to say after using the knife: "The HAP-40 is an unusual knife. It's large, but I personally enjoy having two knives in one. The larger butt end and straighter edge handle all manner of slicing and cutting and the smaller tip end is great for more detailed work. It's unusual in that it's unbalanced, weighted toward the tip, but I have enjoyed that as for such a large knife it just naturally wants to fall into the cut and therefore make it an easier, smoother process. The fact it looks stunning and is sharp as shit doesn't hurt!" |
HANDLE:
The blade is fitted with an octagonal Japanese (Wa) style handle made out of a single piece of luxurious dark ebony wood, renowned for its exceptional hardness and density, which makes it one of the most durable and resistant woods. It is polished to a high gloss, creating a luxurious and elegant appearance and smooth feel that fits into the hand seamlessly. The octagon shape of the handle provides a comfortable and secure grip, allowing for precise control during use.
ABOUT THE BLACKSMITH:
The knife is manufactured at the smithy of Yoshida Hamono in Japan, a family company with an age-long tradition in manufacturing state-of-the-art tools and Japanese swords, i.e., katanas, by hand. Yoshida Hamono has a great deal of experience forging ZDP-189 steel in the traditional manner.

Blade wear depends on the quality of steel, usage and maintenance of the blade. Japanese knives are made of high-quality steels. Follow these tips to keep your Japanese knife in top-notch shape:
✔ Use a wooden, plastic or rubber cutting board.
✔ After use, wash the knives and wipe them dry.
✔ For storage, use a knife holder or a protective knife sheath (saya).
✔ A good cutting technique is your best bet to prolong sharpness.
✔ Use sharpening stones to sharpen the knife.

❗️Don’t wash the knife in the dishwasher.
❗️Don’t use the knife on glass, ceramics, marble or steel surfaces.
❗️Don’t scrape the food off the cutting board with the edge of the blade. Use the spine of the knife instead.
