VG-10 Steel Overview
Composition & Hardness
VG-10 is a stainless steel developed by Takefu Special Steel in Japan. Its composition includes:
- Carbon (1.0%) – Provides hardness and edge retention.
- Cobalt (1.5%) – Enhances toughness and wear resistance.
- Chromium (15%) – Ensures corrosion resistance.
- Vanadium & Molybdenum – Improve grain refinement and strength.
VG-10 typically reaches HRC 60-62, making it hard enough for precise cuts while maintaining decent toughness.
Edge Retention & Sharpening
VG-10 holds an edge well but is easier to sharpen compared to high-carbon steels like Aogami Super. It’s a great choice for those who want a balance between performance and maintenance.
Corrosion Resistance
Thanks to its high chromium content, VG-10 is highly rust-resistant, making it ideal for humid environments or cooks who prefer low-maintenance knives.
Best Uses
- Gyuto, Santoku, and Petty knives
- Home cooks who want durability and ease of care
- Sushi chefs needing stain resistance
Aogami Super Steel Overview
Composition & Hardness
Aogami Super (Blue Super Steel) is a high-carbon, non-stainless steel made by Hitachi Metals. Its key elements include:
- Carbon (1.4-1.5%) – Provides extreme hardness and edge retention.
- Tungsten (2.5%) – Enhances wear resistance.
- Chromium (0.5%) – Minimal rust protection.
Aogami Super reaches HRC 64-66, making it one of the hardest knife steels available.
Edge Retention & Sharpening
Aogami Super holds an edge longer than VG-10 but is harder to sharpen due to its extreme hardness. It’s favored by professionals who prioritize long-lasting sharpness.
Corrosion Resistance
Since it lacks chromium, Aogami Super is prone to rust if not properly maintained. Regular oiling and drying are essential.
Best Uses
- Yanagiba, Deba, and Usuba knives
- Professional chefs who demand razor-sharp edges
- Knife enthusiasts willing to maintain high-carbon steel
VG-10 vs. Aogami Super: Key Differences
| Feature | VG-10 (Stainless) | Aogami Super (Carbon) |
|---|---|---|
| Hardness (HRC) | 60-62 | 64-66 |
| Edge Retention | Good | Excellent |
| Sharpening Ease | Easier | Harder |
| Rust Resistance | High | Low |
| Maintenance | Low | High |
| Price | Mid-range | Premium |
1. Hardness & Durability
- Aogami Super wins in hardness, allowing for a finer, longer-lasting edge.
- VG-10 is tougher, making it less prone to chipping under heavy use.
2. Edge Retention & Sharpening
- Aogami Super retains an edge longer but requires more skill to sharpen.
- VG-10 is easier to maintain for home users.
3. Rust Resistance & Maintenance
- VG-10 is nearly rust-proof, ideal for humid kitchens.
- Aogami Super requires oiling and careful drying to prevent corrosion.
4. Price & Availability
- VG-10 knives are more affordable and widely available.
- Aogami Super knives are premium-priced, often hand-forged by master smiths.
Which Steel Should You Choose?
For Home Cooks
- VG-10 is the better choice due to its balance of performance, ease of sharpening, and rust resistance.
For Professional Chefs
- Aogami Super excels in high-end kitchens where extreme sharpness and edge retention are critical.
For Knife Enthusiasts
- If you enjoy maintaining high-carbon steel, Aogami Super offers unparalleled performance.
- If you prefer low-maintenance convenience, VG-10 is a reliable option.
Frequently Asked Questions
1. Is Aogami Super better than VG-10?
It depends on your needs. Aogami Super is harder and holds an edge longer, but VG-10 is more corrosion-resistant and easier to maintain.
2. Does Aogami Super rust easily?
Yes, it requires regular oiling and drying to prevent rust.
3. Can VG-10 get as sharp as Aogami Super?
VG-10 can achieve a very sharp edge, but Aogami Super can reach a finer, longer-lasting sharpness due to its higher carbon content.
4. Which steel is best for a beginner?
VG-10 is more forgiving and easier to care for, making it ideal for beginners.
5. Are Aogami Super knives worth the price?
For professionals and enthusiasts, yes—its performance justifies the cost. For casual cooks, VG-10 may be more practical.
Final Thoughts
Both VG-10 and Aogami Super are exceptional steels, but they serve different purposes. If you prioritize low maintenance and durability, go for VG-10. If you demand ultimate sharpness and don’t mind upkeep, Aogami Super is the superior choice.
Ultimately, the best steel depends on how you use your knife and how much care you’re willing to invest. Whichever you choose, Japanese knife craftsmanship ensures a high-quality blade that will elevate your cooking experience.
