○ Rust-resistant

○ Perfectly balanced for comfort

○ Bamboo “Saya” (鞘) - blade guard included

○ Sustainably-grown bamboo box

    Rediscover the art of cooking with KOTAI knives. Experience the sharpness and precision of handcrafted blades made from the finest materials. Elevate your culinary creations to new heights with the perfect combination of tradition and modern innovation.

  • Lasting Performance

    440C contains twice as much carbon as other premium steels. The blade, heat treated to HRC 60 +/- 1 hardness, keeps its razor-sharp edge cut after cut.

  • Ergonomically Engineered

    The perfect weight distribution and hand-polished ebony handle have been designed for you to cut effortlessly through the toughest food without compromising on comfort.

With a blade long enough for serious cooking but more agile than a full-sized Kiritsuke, the Bunka Petty is ideal for quick and precise cuts.

KOTAI’s Bunka Petty is made of Japanese 440C, a premium steel that balances a high carbon content for hardness, sharpness and edge retention with the perfect amount of chromium to prevent corrosion.

FAQ

What type of steel is used for the blade? Will it rust?

This knife is made of 440C steel from Japan. 440C is a high-carbon stainless steel, meaning it combines the properties of high-carbon steel (very hard due to its high carbon content of 0.95%+) with vacuum heat treatment, making it extremely sharp and capable of retaining its edge for a long time. longer than other steels) and stainless steel (resistance to corrosion and staining). Thus, the blade will not rust, but you must care for it properly by washing it with soapy water and drying it quickly after use.

Do not put it in the dishwasher or leave it soaking in the sink.

Is it worth buying this knife, or should I just buy a €30 knife from Ikea?

A cheap knife often ends up costing you more over time. It can break or lose its sharpness quickly, and low-quality steel simply will not hold an edge, no matter how many hours you spend sharpening it. Sooner or later, you may find yourself buying a new knife every year.

There are many inexpensive knives on the market that do not meet even basic standards, and very few affordable options for passionate home cooks who need reliable tools to support their craft or hobby without paying extra just for a brand name. Choose a KOTAI knife today and invest in a lifetime of safe, enjoyable cooking.
