HAP-40 Petty Black 135mm (5.3") blade paired with our SharpEdge stabilized wood handles in grey/orange/emerald green/light brown.

HAP-40 Petty Black 135mm (5.3") is a small kitchen knife from our HAP-40 series which we designed in collaboration with the Yoshida Hamono smithy.

We paired this blade with our custom maple burl handles in four different colors:

TOKYO NIGHT: Traditional Japanese handle with a modern twist in a dark color named Tokyo Night. The color of these handles varies from light to dark grey, with soft or deep hues of red and swirls of cream. If you like a particular hue, please contact us before placing an order.   
OKINAWA REEF:
Traditional Japanese handle with a modern twist in a soothing, emerald green color named Okinawa Reef. It feels like immersing your hand in shimmering coastal waters during summer.
→ KYOTO SUNSET: Traditional Japanese handle with a modern twist in an orange color named Kyoto Sunset. It feels like holding something smooth and warm in your hand – a glow in the sky at sunset or a burst of bright autumn color.
→ TOTTORI SAND: Traditional Japanese handle with a modern twist in a sandy brown color named Tottori Sand. Inspired by the infinitely swirly Tottori sand dunes found in the western part of Japan.

BLADE SHAPE:
Petty or utility knives are basically a smaller version of gyutos or chef's knives, intended for all those smaller tasks where larger and wider knives are deemed unwieldy. A must-have in every kitchen, this small general-purpose knife is perfect for peeling and slicing fruit and vegetables.

HANDLE:
We chose a universal, octagonal shape that comfortably fits the hands of both right- and left-hand users. It offers a firm grip for easy and comfortable use.

Handles are made of natural maple wood, which undergoes a special procedure of stabilization with resin. This ensures a long service life of the handle. During this process of stabilization, a color pigment is added which penetrates the wood in different ways, creating unique patterns. This makes every handle one-of-a-kind.

 Color and patterns of handles may vary from what is seen in the pictures. If you like a particular color hue, please contact us before placing an order.

STEEL:
The secret of this knife lies in its hard core made of a somewhat exotic 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 made from it 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. It is extremely tough, and so not as likely to chip along the edge as the steel used in traditional knives.

LAMINATION:
Osamu-san chose a warikomi (also called “split and insert”) method. A glowing hot piece of iron is split and a piece of steel is inserted. The material is then forged into one piece composed of a very hard steel core in a jacket of 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 this look is 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.
