Blue (Aogami) Super

Has even higher tungsten and carbon content than Aogami #1, making it the sharpest, hardest, and most long-lasting Yasugi Steel in existence. However, it also gets chipped easier due to its reduced tenacity and toughness. Aogami Super and #1 have rock-solid blades, making them difficult to sharpen. They require proper whetstone selection and grinding techniques to bring out their intended performance.
