White Steel #1 is a premium refined steel from the Shirogami series, recognized for its exceptionally high carbon content. This gives the blade outstanding sharpness, excellent cutting performance, and precise cutting control. With an extremely pure composition, White Steel #1 allows Japanese craftsmen to control every step of the forging process. It creates knives that not only deliver exceptional performance but also embody spiritual depth, cultural heritage, and enduring quality.
What is White Steel #1 (Shirogami #1)?
White Steel #1, also known as Shirogami #1 steel, is a high carbon Japanese steel prized for its exceptional sharpness and ability to take a very fine edge. Manufactured by Hitachi in Japan, this steel contains approximately 1.25–1.35% carbon, giving it a significantly higher carbon content than many other steels like
White Steel #2.
However, this high carbon content also makes it more brittle than steels with lower carbon content.
With a Rockwell hardness of 62–64 HRC, White Steel No.1 is notably harder than most Western steels. Its exceptional purity minimizes impurities in the steel, ensuring a clean structure that contributes to both performance and longevity.
Benefits of White Steel #1 Knives
White Steel #1 knives are renowned for their razor‑sharp edge and the ability to hold a remarkably keen edge. With a high carbon composition and remarkable purity, these blades deliver precise, clean cuts that professional chefs consistently rely on.
Many describe the experience as slicing through food with virtually no resistance, as if the knife moves effortlessly through each ingredient.
Key advantages of White Steel #1:
- Exceptional Sharpness: White Steel #1 features a rich carbon composition that allows the blade to be sharpened to an extremely fine and keen edge, perfect for demanding culinary tasks.
- Excellent Edge Retention: The blade holds its sharpness remarkably well over time, making it ideal for work that requires a consistently sharp edge.
- Relatively Easy to Sharpen: Despite its hardness, White Steel #1 can be sharpened with relative ease when using the proper tools and technique.
- Ideal for Delicate Tasks: Its sharpness and stability make it an excellent choice for slicing soft or delicate ingredients such as sashimi, where precision is critical.
- Distinct Cutting Feel: These knives provide clear tactile feedback with each cut, offering chefs greater control and confidence during preparation.
- Natural Patina Development: Over time, the blade develops a beautiful patina that not only adds character but also offers mild protection against rust.
Comparing White Steel #1 and White Steel #2
White Steel #1 and White Steel #2 are both part of the renowned Shirogami series from Japan and are produced by Hitachi Metals. These steels are known for their high purity and excellent cutting performance.
White Steel #2 is the original form, containing approximately 1.05–1.15% carbon. It offers impressive sharpness, is easy to sharpen, and provides good toughness. This makes it a great choice for everyday use, especially for those who want a sharp, reliable knife that is relatively easy to maintain.
White Steel #1 is made by further refining White Steel No.2 and adding more carbon, increasing its carbon content to about 1.25–1.35%. As a result, it reaches a higher level of hardness and can achieve an even finer edge with better edge retention.
How Should You Care for Your White Steel #1 Knife?
White Steel #1’s elevated carbon levels demand thoughtful care to maintain sharpness and prevent rust.
- Hand wash it with warm soapy water immediately after use, dry it thoroughly, and apply a thin coat of camellia or mineral oil to prevent rust.
- Store the knife in a dry place such as a knife block, magnetic strip, or wooden sheath.
- Avoid storing it in damp drawers or next to other metal tools.
- Sharpen regularly with quality whetstones between 1000 and 6000 grit.
- Use the knife with care and rinse off acidic ingredients quickly.
- Let a natural patina develop over time to help protect the blade.
With proper care, a White Steel #1 knife from Lewis Knife will provide decades of exceptional cutting performance and develop character that makes it uniquely yours.
