Detailed Breakdown
Why Aogami #2 is the "Standard":
Versatility: It is the most common carbon steel used by Japanese blacksmiths for a reason. It holds a very sharp edge for a long time but remains "tough" enough that it doesn't chip every time it hits a hard vegetable or a wooden board.
Sharpening: It is much friendlier on whetstones than #1. You can bring it back to a razor edge quickly, making it ideal for home cooks and professionals alike.
Why Choose Aogami #1?
Endurance: The higher carbon and tungsten content create more hard carbides. This means it will stay at "peak sharpness" longer than #2.
The Pro's Choice: It is favored by chefs who do repetitive slicing for hours and don't want to stop to strop their knife. However, because it is harder, it is more "glass-like" and requires more delicate handling to avoid damage.
The Verdict
Choose Aogami #2 for your first high-end knife, or for a Gyuto (Chef's knife) that you use for everything. It is the best balance of performance and durability.
Choose Aogami #1 if you are an experienced user who wants maximum edge life and doesn't mind spending extra time on the sharpening stones.
