Blue Steel #1 (Aogami #1) delivers exceptional sharpness and edge retention, making it a preferred choice for high-end Japanese knives crafted for chefs and skilled artisans. It builds upon Blue Steel #2 by increasing the carbon content and adding chromium and tungsten, resulting in greater hardness and cutting performance. However, due to its high hardness, Blue Steel #1 can be brittle and requires careful handling—hand wash, dry immediately, and avoid twisting cuts during use.
