For most users, Aogami Super (AS) is the "better" steel because it offers the highest performance in terms of edge retention and cutting efficiency. Aogami #2 is preferred by those who want a high-quality "workhorse" that is easier to sharpen and more affordable.
Quick Comparison: Aogami #2 vs. Aogami Super
Feature | Aogami #2 (Blue #2) | Aogami Super (Blue Super) |
|---|---|---|
Edge Retention | High; very reliable | Extreme. The longest-lasting edge. |
Max Hardness | 61–63 HRC | 64–67 HRC. Harder and thinner. |
Toughness | Higher. Less prone to chipping. | Moderate. Brittle due to extreme hardness. |
Sharpening | Easier. Fast and responsive. | Challenging. Requires more time/effort. |
Maintenance | High (Reactive) | High (Often found with stainless cladding). |
Best For | All-purpose daily use. | High-volume prep; "laser" performance. |
Detailed Analysis
Why Aogami Super is often considered "Better":
The King of Carbon Steel: AS contains the highest amount of carbon (~1.45%) plus added Vanadium, which makes it incredibly wear-resistant. It stays sharp significantly longer than Aogami #2.
Laser Cutting: Because the steel is so hard, blacksmiths can grind the blade to a very thin, sharp edge that glides through food with almost no resistance.
Modern Construction: Most Aogami Super knives come stainless-clad, meaning only the very edge is reactive carbon steel, making it much easier to maintain than a fully reactive Aogami #2 blade.
Why Aogami #2 might be "Better" for you:
Durability: Aogami #2 is slightly less brittle than AS. If you are occasionally rough with your knives, #2 is more likely to survive without a micro-chip .
Ease of Sharpening: Aogami Super can be frustrating to sharpen for beginners because it resists abrasion. Aogami #2 is much friendlier on whetstones and takes a very "crisp" edge quickly.
Price: Aogami #2 knives are generally 20-30% more affordable than Aogami Super knives.
The Verdict
Choose Aogami Super if you are a professional or a serious home cook who wants the absolute best edge life and doesn't mind the extra effort (and cost) of sharpening a very hard steel.
Choose Aogami #2 if you want a reliable, balanced workhorse that is easy to maintain and sharpen, providing a great "entry point" into premium Japanese carbon steel.
