Tadafusa Knife Studio All-Purpose Knife 170mm Santoku [HK-2] Sanjo City, Niigata Prefecture, Tsubame-jo, Tadafusa, Blacksmith Brand

“The 3 Essential Knives” from a long-established knife manufacturer, designed for long-term use. Established in 1948 in Sanjo City, Niigata Prefecture, a leading metalworking and hardware production area in Japan, Tadafusa is a long-established knife manufacturer that utilizes traditional forging techniques to produce a wide range of blades, from household to professional use.

The "Hocho Kobo Tadafusa" series, born in 2012 with product designer Fumie Shibata, is synonymous with the company. It narrowed down the specialized and often difficult-to-choose knives into a simple lineup of "The 3 Essentials (Santoku, Petty, Bread Knife)" and "The Next One," to be chosen based on cooking skill, gaining wide support.
The bread knife, in particular, is an innovative product that allows for clean cuts without producing crumbs, thanks to serrations only at the tip, and can even be sharpened at home.

In terms of functionality, it features a three-layer blade structure with "SLD steel" sandwiched between stainless steel, achieving both sharp cutting performance and rust resistance. The handle uses patented "antibacterial carbonized wood," which maintains the warmth of natural wood while offering high hygiene by preventing bacterial growth. Furthermore, the brand offers a resharpening service where the product packaging doubles as a "return box" for shipping to the factory. This commitment to "using one tool carefully for a long time" is a major appeal of the brand, aligning with modern lifestyles.

Effortlessly slice tomatoes thinly. Exceptional sharpness.


Even soft cream puffs can be cut cleanly without losing their shape.

This knife is called "Santoku" because it can be used for preparing meat, fish, and vegetables. Its pointed tip gives it a wide range of uses, making it the most commonly used knife in households.

It's recommended for those who "don't know which knife to choose" because it can be used for a wide range of tasks, from preparing vegetables to slicing meat and preparing fish.
It's an all-purpose knife that's easy to choose for those who want to replace a dull knife or who want to own a proper knife for the first time.

The blade has a complete three-layer structure combining stainless steel and SLD steel. It uses SLD steel as the core material for sharp cutting performance, sandwiched between stainless steel on the outside. This design allows you to enjoy the sharpness unique to steel while providing a balance that makes it easy to handle as an everyday tool.

The blade has a complete three-layer structure with SLD steel sandwiched between stainless steel.

【Hitachi SLD Steel】

It contains chromium similar to stainless steel, and a significant amount of carbon, molybdenum, and vanadium. Therefore, it does not rust like carbon steel (white paper steel, blue paper steel). (It does not mean it won't rust at all.)

As it is a hard and tenacious special alloy steel, it cuts well and retains its sharpness for a long time.
*After use, wipe off moisture thoroughly and store in a suitable environment.

Easy to use size


An antibacterial carbonized wood handle born from Tadafusa's patented technology (Patent No. 4029427).

About 【Antibacterial Carbonized Wood】

Made from antibacterial carbonized wood born from patented technology. (Patent No. 4029427)

This is wood that has been smoked in a furnace to a state just before charring. When bacteria adhere to this wood, there is almost no moisture or nutrients to feed them, preventing their growth and causing them to die.

Since the wood is smoked, it has a unique scent, but it is not artificial or chemical fragrance.

Comes with a gift box, also suitable for mailing for knife sharpening service.

The blade length is approximately 17 cm, the total length is approximately 30 cm, and it weighs approximately 135 g, making it a convenient size for daily cooking. Neither too large nor too small, it can be used for a wide range of tasks, from preparing vegetables to cooking meat and fish.

The rounded handle fits comfortably in the hand, and the natural texture of the wood gives it a warm, kitchen-tool feel. The blade features the Tadafusa logo engraving. Simple yet appealing for its functional beauty.

Since it comes in a dedicated paper box, it is recommended not only for personal use but also as a gift for cooking enthusiasts for occasions such as wedding gifts, new home celebrations, moving gifts, and birthdays.

The box can also be used to mail the knife for sharpening service, so it's a good idea to keep it safe instead of throwing it away.

While we strive to maintain stock, production and arrival may take 7 to 10 days if an item is out of stock. If it will take longer, we will inform you of the new delivery date. Please feel free to inquire about stock status, arrival times, etc.

Compared to all-stainless steel knives, Hocho Kobo Tadafusa knives offer superior sharpness, but require a little more care in daily maintenance. Since the cutting edge uses steel (SLD steel), rust may occur depending on the care and storage environment. Rust can occur even overnight, depending on the care and storage environment. We hope you enjoy both the comfortable sharpness and the care and resharpening process.

After use, thoroughly wash off all dirt from the knife with hot water, wipe off all moisture completely, and store it in a safe place.

If you cut foods with high salt or acidity, such as pickles or lemons, be sure to wash off the dirt thoroughly.

Do not put it in a dishwasher, dish dryer, microwave, or oven. This may cause damage.

Even a sharp blade will gradually dull with each use. Sharpen it with a whetstone at least once every three months. If you are not confident in sharpening, please leave it to the workshop.
