Tadafusa Knife Studio All-Purpose 170mm Santoku Knife [HK-2] Niigata Brand tadafusa

The "Three Basic Knives" from a Long-Established Knife Manufacturer, Cherished for a Lifetime. Founded in 1948 in Sanjo City, Niigata Prefecture, one of Japan's leading metalworking and hardware production areas, "Tadafusa" is a long-established knife manufacturer that utilizes traditional blacksmithing 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 simplified the selection of specialized and often difficult-to-choose knives into a basic lineup of "three basic knives (santoku, petty, and bread knife)" and "the next knife" to be chosen according to one's cooking skill, gaining wide support.
In particular, the bread knife is an innovative product that allows for beautiful cuts without producing crumbs by having serrations only at the tip, and it can also be resharpened at home.

In terms of functionality, the blade adopts a three-layer structure with "SLD steel," which combines sharp sharpness and rust resistance, sandwiched between stainless steel. The handle uses "antibacterial carbonized wood," a patented technology, achieving high hygiene that prevents bacterial growth while retaining the warmth of natural wood. Furthermore, the brand offers a sharpening service where the product packaging can be used as a "return box" to the factory, and this commitment to "using one tool carefully for a long time" in line with modern lifestyles is also a significant appeal of the brand.

Effortlessly slices tomatoes thinly. Exceptional sharpness.

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

It's suitable for various tasks, from preparing vegetables to slicing meat and cooking fish, making it an excellent choice for those who are unsure which knife to pick.
This versatile knife is also recommended for those looking to replace a dull knife or those who want to invest in a quality knife as their first.

The blade features a complete three-layer structure combining stainless steel and SLD steel. SLD steel, which produces sharp cuts, is used as the core material, with stainless steel sandwiching it on the outside. This design allows users to enjoy the sharpness unique to steel while maintaining a balanced ease of use for everyday tools.

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

【Hitachi SLD Steel】

It contains chrome comparable to stainless steel, and a significant amount of carbon, molybdenum, and vanadium. Therefore, it does not rust like carbon steel (white steel, blue steel). (It does not mean it will not rust at all).

As it is a special alloy steel that is hard and tenacious, it cuts well and retains its sharpness for a long time.
*After use, wipe off moisture thoroughly and pay attention to the storage environment.

About 【Antibacterial Carbonized Wood】

Uses antibacterial carbonized wood created from patented technology. (Patent No. 4029427)

It is wood that has been smoked in a kiln, brought to a state just before charcoal. When bacteria attach to the wood, there is almost no moisture or nutrients for them to thrive, preventing bacterial 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-ready cosmetic box. Can also be used as a mailing box for knife sharpening services.

The blade length is approximately 17 cm, the total length is approximately 30 cm, and it weighs about 135g, making it a convenient size for daily cooking. It's neither too big nor too small, so it can be widely used for everything 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. While simple, its beauty as a tool is also appealing.

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

The box can also be used to mail the knife for the sharpening service, so it's a good idea to keep it without discarding it.

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 care and storage conditions. Rust can even appear overnight depending on care and storage. Please enjoy both the comfortable sharpness and the maintenance and re-sharpening process.

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

Especially after cutting foods high in salt or acid, such as pickles or lemons, wash off dirt thoroughly.

Do not place in dishwashers, dish dryers, microwaves, or ovens. This may cause damage.

Even sharp blades will gradually lose their edge with use. Sharpen your knife with a whetstone at least once every three months. If you are not confident in sharpening, please entrust it to the workshop.
