  • This is a carbon steel knife made from thin, hard steel.
  • Hand wash and towel dry after use. Do not air dry or place in the dishwasher.
  • Expect oxidation (color change, staining, spotting) with use.
  • Prolonged exposure to moisture or food debris will cause rust; remove any rust with a light abrasive.

Aogami 2 (Blue Paper #2)

Carbon (C): 1.1–1.2% | Tungsten (W): 1.1–1.5% | Chromium (Cr): 0.3%

Aogami 2 is a well-balanced Hitachi carbon steel commonly hardened to around 60–63 HRC—about one point softer than Aogami 1—which gives it excellent edge retention with added toughness. Its slightly lower carbon content means it loses its razor edge a bit sooner but holds a strong working edge for long periods, making it a favorite “sweet spot” steel for daily-use kitchen knives. More forgiving and less brittle than Aogami 1, it can take thin edges without chipping and excels in hard-use kitchen or woodworking applications.

Though fully reactive and prone to patina, it sharpens easily to a keen, refined edge and responds beautifully to both fine and toothy finishes. Aogami 2 is widely used by Japanese makers for workhorse knives and is often stainless-clad for user-friendly maintenance.
