Hayabusa Santoku HAP-40 Damascus 180mm (7.1")

Hayabusa Santoku HAP-40 Damascus 180mm is a multi-purpose Japanese kitchen knife, suited for preparing meat, fish and vegetables. It’s a nonconformist piece that just screams futurism. Featuring a classic western style handle and a brazen look, it’s quite a unique knife. The wavy damascus curves on the blade are sharp and steep, reminiscent of high-frequency waves and synchronous with up-and-down chopping motions.

Made from HAP-40 steel, which is one of the most technologically advanced steels renowned for its extreme hardness, excellent sharpness and edge retention it provides to the knives. If you’re not a fan of sharpening your knives, this one is for you, as you really won’t have to do it often.

Fun fact: Hayabusa santoku shares its name with the peregrine falcon (ハヤブサ), the fastest member of the animal kingdom. This knife may not reach speeds upwards of 350 km/h, but chopping with it will feel just as fast.

BLADE SHAPE:
The Japanese word Santoku roughly translates to “knife of three virtues” and may refer to the wide variety of ingredients that the knife can handle: meat, fish and vegetables, or to the tasks it can perform: slicing, chopping and dicing - the emphasis being on the number 3 (San).

Its distinguishing shape makes santoku easy to identify: the cutting edge is fairly straight (giving santoku a limited rocking motion), while the spine of the blade curves towards the tip continuously at an approximately 60-degree angle, making it resemble a sheep's foot.

STEEL:
This knife’s hard core is 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.

LAMINATION:
The core layer consisting of the hard HAP-40 steel was sandwiched between two sheets of softer damascus pattern steel. This technique is called san-mai and is used to protect the hard (but delicate) core from outside factors and physical impacts, which could lead to breakage.

GEOMETRY:
It has a double bevel (symmetrical) blade.

BLADE FINISH:
The blade has a unique damascus finish with sharp and steep curves that give the knife a futuristic appearance. The clad line is interesting as well, with consistent curves that aren’t frequently seen on Japanese knives.

HANDLE:
Classic western (Yo) style handle made from black micarta.
