Tadafusa Knife Studio All-Purpose 125mm Petty Knife [HK-3] Sanjo City, Niigata Prefecture, Tsubame-Sanjo Tadafusa Blacksmith Brand Petty Knife

The "Basic Three" from a long-established knife manufacturer, cherished for generations. Tsubasa Co., Ltd., founded in 1948 in Sanjo City, Niigata Prefecture, a leading metalworking and hardware production area in Japan, is a long-established knife manufacturer that utilizes traditional blacksmithing techniques to produce a wide range of blades for both household and professional use.

The company's signature product is the "Tadafusa Knife Studio" series, which was launched in 2012 in collaboration with product designer Fumie Shibata. This series simplified the selection of specialized and often confusing knives into a straightforward lineup of "Basic Three" (santoku, petty, and bread knife) and "Next One" knives chosen according to one's cooking skill, earning widespread acclaim.
The bread knife, in particular, is an innovative product that allows for beautiful, crumb-free slicing by having serrations only at the tip, and can even be sharpened at home.

In terms of functionality, the blades feature a three-layer structure with "SLD steel" (known for its sharpness and rust resistance) sandwiched between stainless steel. The handles use patented "antibacterial carbonized wood," which retains the warmth of natural wood while achieving high hygiene by preventing bacterial growth. Furthermore, the brand offers a sharpening service where the product packaging can be used as a "return box" to the factory, demonstrating its commitment to the modern lifestyle of "cherishing and using one tool for a long time." This commitment is a significant appeal of the brand.

"Tadafusa Knife Studio" knives, while offering a sharper edge compared to all-stainless steel knives, require a bit more attention in daily care. As the cutting edge uses steel (SLD steel), rust may occur depending on care and storage environment. Rust can even develop overnight depending on care and storage conditions. Please enjoy the pleasant sharpness along with the maintenance and resharpening process.

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

Especially when cutting highly acidic foods with high salt content, such as pickles or lemons, thoroughly wash off any dirt.

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

Even sharp blades gradually lose their edge with use. Sharpen your knife with a whetstone at least once every 3 months. If you are not comfortable sharpening, please entrust it to the workshop.

For detailed handling instructions, please refer to the instruction manual included with the product.
