Aogami vs Shirogami: What’s the Difference?
Sep 27, 2026
Aogami and Shirogami are both Japanese carbon-steel families; neither is universally better. Aogami includes additional alloying elements compared with the simpler Shirogami compositions, which can influence wear resistance and edge retention. In an actual knife, heat treatment and geometry can matter more than the name alone.
What is Aogami?
Aogami, or Blue Paper steel, is a family of high-carbon steels. Aogami #2 appears in our current knife range. It is reactive, can form patina and needs prompt drying.
What is Shirogami?
Shirogami, or White Paper steel, is another high-carbon family. Shirogami #2 is used in several traditional knives in our range. It is also reactive and requires corrosion care.
Which is easier to sharpen?
Shirogami is often discussed for a straightforward sharpening feel, but hardness, heat treatment, edge geometry and stones strongly affect the real experience.
Which holds an edge longer?
Aogami's additional alloying can increase wear resistance, but a badly treated Aogami knife can still perform worse than a well-made Shirogami knife. Compare finished knives, not labels alone.
Which needs less maintenance?
Both are carbon steels and should be washed and dried promptly. Stainless cladding can reduce the exposed reactive surface on either type.
Which should you buy?
Choose the knife whose shape, geometry, maker and care requirements suit you. Treat the steel family as one part of that decision.
