DESCRIPTION

White Steel No.1 is made by further refining White Steel No.2 and adding more Carbon. The extra Carbon allows it to achieve a slightly higher HRc. than White Steel No.2, but also makes it a bit more brittle. White No.1 is very popular with professional chefs who make traditional Japanese cuisine because it can be sharpened to an exceedingly fine edge, has very good edge retention and is easy to re-sharpen.For knives, mirror finishing not only can enhance appearance but also can increase sharpness and durability.

FAQ

What’s the difference between carbon steel and stainless steel?

Carbon steel offers exceptional sharpness and edge retention, but requires careful maintenance to avoid rust. Stainless steel is easier to care for and resists corrosion, making it ideal for everyday use.

Can I request custom engraving?

Yes. Laser engraving is available as an optional service. You can add your name, message, or kanji to the blade handle or spine.

Do you ship internationally?
