Japanese Blade Steel- SUS 405/ Aogami 2 (Blue) laminate steel by Proterial. Imported from Japan by Vonhelmick Knife Co. LLC. Proterial (formerly Hitachi Metals) Aogami 2 (Blue Steel #2) is a premium high-carbon Japanese steel renowned for excellent edge retention ( HRC) and sharp cutting performance, often utilized in high-end knives. When laminated with stainless SUS 405, it combines a rust-resistant body with a superior, sharp edge, though the edge still requires maintenance.
Core Layer: Aogami 2 (Blue Paper Steel No. 2)
The center of the laminate is a premium Japanese high-carbon steel known for its exceptional cutting ability.
Performance: It achieves a high hardness of 62–65 HRC, providing outstanding edge retention and a "silky" cutting feel.
Composition: Contains approximately 1.05–1.15% Carbon, with added Tungsten (1.0–1.5%) and Chromium (0.2–0.5%) to increase wear resistance and toughness compared to "White" steels.
Maintenance: As a carbon steel, the exposed edge is reactive; it will develop a patina over time and can rust if not dried immediately after use.
Cladding Layer: SUS 405 Stainless Steel
The outer layers consist of SUS 405, a ferritic stainless steel that sandwiches the core to improve durability and ease of maintenance.
Corrosion Resistance: With 11.5–14.5% Chromium, it shields the majority of the blade from rust and staining, making the knife more practical for daily kitchen use.
Properties: SUS 405 is relatively soft and ductile, which helps protect the harder, more brittle core from snapping or chipping.
Non-Hardenable: Unlike the core, this cladding does not harden significantly during heat treatment, maintaining its flexibility.
Key Benefits of this Laminate
Best of Both Worlds: You get the extreme sharpness and easy sharpening of professional-grade carbon steel with the rust-resistance of a modern stainless knife.
Forgiving Performance: Aogami 2 is often recommended as the "benchmark" for blue steels because it strikes a better balance between toughness and edge retention than the more brittle Aogami 1 or Super Blue.
Ease of Sharpening: Despite its high hardness, the core is praised for being relatively easy to sharpen on whetstones compared to high-alloy stainless steels.

Thickness is 6mm
