• Blue Steel #2

  • Blue Steel #2 is a high-quality steel that combines stable sharpness with excellent durability. With a carbon content of approximately 1.05–1.15%, Blue Steel #2 offers sharpness comparable to White Steel, but lacks the hardness of Blue Steel #1. Instead, it excels in wear resistance compared to White Steel, making it particularly recommended for professional chefs who handle large volumes of ingredients daily.

  • The edge of Blue Steel #2 provides a unique cutting sensation, where the blade glides into the food rather than slicing through it abruptly. Even as its sharpness diminishes slightly, it maintains a stable cutting performance. This characteristic makes Blue Steel #2 highly popular among chefs who prioritize long-lasting sharpness and durability.

  • Blue Steel #2 is known for its ease of handling and sharpening. It is also versatile in its application, being easy to process, resilient, and resistant to shock. These attributes make it suitable for a wide range of knife shapes and types.

FAQ About Blue Steel #2

Knife_forging_process

What is Blue Steel?

Blue steel is a high-grade steel that is created by adding chromium, tungsten, and other elements to white steel to enhance its heat treatment properties and wear resistance. It is priced slightly higher than white steel. Knives made from this steel may seem difficult to sharpen for those not accustomed to it, but once sharpened, they maintain their edge for a longer period, resulting in prolonged sharpness.

What is the difference between Blue Steel #1 and #2?

The difference between Blue Steel #1 and #2 lies in their hardness. The numbers (#1, #2, #3) represent the hardness levels of the steel, with lower numbers indicating greater hardness. Consequently, as the steel becomes harder, the sharpness of the blade improves. Therefore, Blue Steel #1 offers the best sharpness, followed by #2, and then #3. Furthermore, harder steel also tends to retain its sharpness for a longer period, enhancing its edge retention capabilities.

What is the difference between Blue Steel and White Steel?

The difference between Blue Steel and White Steel lies in their composition. Blue Steel is an alloy steel made by adding a small amount of tungsten and chromium to White Steel. Due to its increased resilience and resistance to abrasion, Blue Steel is said to maintain its sharpness longer compared to White Steel.

What is the maintenance method for Blue Steel #2?

For maintaining Blue Steel #2 and other carbon steel knives, it's crucial to prevent rust formation. After use, always apply a rust-preventive oil to the blade. It's recommended to use non-drying oils such as camellia oil or olive oil. Additionally, applying beeswax or similar lubricant between the spring and washer can enhance the smoothness of blade opening and closing.
