The Hayabusa Petty HAP -40 120mm is a small Japanese kitchen knife that comes in handy when a larger chef's knife is too unwieldy for the task. Its HAP -40 steel blade is thin and precise. The knife stands out for its sharpness, edge retention and ease of maintenance. HAP -40 steel is one of the most technologically advanced steels, known for its extreme hardness, excellent sharpness and edge retention that it gives to knives. With this knife, frequent sharpening is a thing of the past, as its exceptional edge retention ensures long-lasting performance. If you prefer a low-maintenance knife that doesn't compromise on quality and performance, the Hayabusa Petty HAP -40 120mm is the perfect choice for you.

Fun fact: Hayabusa petty 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.

Petty knives are designed for smaller tasks on and off the cutting board. It's an indispensable knife in any kitchen and can be used for peeling, mincing, paring and decorating food.

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.

The core layer consisting of the harder Ginsan steel was sandwiched between two layers of softer 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.

It has a double bevel (symmetrical) bladeThe cutting edge is sharpened to a 50/50 angle and stays sharp even after hours of constant use.

The minimalistic-looking, highly polished (also called migaki finish - see article Blade Construction: Blade Finish for more) blade is extremely thin, which allows the user to work precisely even with the smallest pieces of ingredients. 

The Hayabusa Gyuto Ginsanko 210 mm features an octagon Japanese (Wa) style handle made out of wenge wood, complemented by an epoxy ferrule. The octagon shape of the handle provides a comfortable and secure grip, allowing for precise control during use. Wenge wood is known for its durability and attractive grain pattern, making it a popular choice for knife handles. The epoxy ferrule adds strength and stability to the handle, ensuring long-lasting performance.

☝️ Japanese kitchen knives in our store are handmade from natural materials. Slight variations in color, texture, weight and other dimensions are possible. We try to give a good photographic representation of our products, however computer screen resolution and colors do vary, so products might not look exactly as they are seen on screen.

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 leave the knife in the sink. Wash it by hand.
❗️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.
❗️Knife is a tool intended for specific use - cutting food. It is not a can opener, screwdriver, trowel, wire cutter, hammer etc.
