Aogami/ Blue Steel Knives

What Is Blue Steel?

Aogami or Blue Steel is a high-carbon steel alloy. It typically consists of 1.0-1.3% carbon content, similar to what you might find in Shirogami or White Steel. The difference is the addition of two elements — tungsten and chromium.

While the high carbon content imbues it with incredible hardness and lightness, the tungsten and chromium improve its durability and abrasion resistance as compared to White Steel. While Blue Steel is generally tougher and more rust-resistant than White Steel, it’s also harder to sharpen.

Aogami Super or Blue Super Steel is similar to Aogami, but with the addition of molybdenum and vanadium to further improve corrosion resistance and strength, respectively.
