VG-10 vs AUS-10
The two mid-premium Japanese stainless steels most home cooks will encounter. In blind testing, indistinguishable to 95% of users in the first six months of use. The differences are real but subtle, and mostly about sourcing economics.
Both are excellent. The retail price gap is bigger than the performance gap.
VG-10 is the more famous name and has a slight edge-retention advantage in controlled testing. AUS-10 is marginally easier to sharpen and typically reaches the buyer at 20-30% lower retail because the brand markup is lower. For a cook who uses a knife daily at home for a year, the difference is imperceptible. For a professional running controlled edge tests weekly, VG-10 wins by a small margin.
What's actually different
| Element | VG-10 | AUS-10 | Why it matters |
|---|---|---|---|
| Carbon (C) | ~1.00% | ~1.05% | Enables hardness; roughly equivalent |
| Chromium (Cr) | 14.5-15.5% | 13-14.5% | VG-10 slightly more corrosion-resistant |
| Molybdenum (Mo) | 0.9-1.2% | 0.1-0.3% | VG-10 has more; improves edge retention |
| Vanadium (V) | 0.1-0.3% | 0.1-0.3% | Equivalent |
| Cobalt (Co) | 1.3-1.7% | None | VG-10's signature; lets it reach 62 HRC without brittleness |
| Maker | Takefu Special Steel (Fukui) | Aichi Steel Corp (Aichi) | Different mills, different supply economics |
The meaningful difference is cobalt. VG-10's cobalt content is what lets Takefu push the steel to 62 HRC without glass-brittleness. AUS-10 doesn't have cobalt and caps practically at 61 HRC. That 1-point HRC difference translates to slightly better edge retention and slightly more chipping risk in VG-10. In daily cooking, you won't notice it.
What we actually measured
Out-of-box edge test (paper cut + tomato)
Our testing on a Tojiro DP (VG-10) and our Okami Premium (AUS-10 Damascus) from factory:
- VG-10: cut through printer paper cleanly on first pull, tomato slice at 4 seconds.
- AUS-10: cut through paper cleanly on first pull, tomato slice at 4 seconds.
- Verdict: tied at factory edge.
30-day edge retention (daily home use, ceramic honing)
- VG-10: still passed paper cut at day 30, noticeably less glide on tomato skin.
- AUS-10: passed paper cut at day 30, same tomato glide reduction.
- Verdict: functionally equivalent for home cooking.
Sharpening on 1000/6000 waterstone
- VG-10: 18 minutes to restore factory edge.
- AUS-10: 14 minutes to restore factory edge.
- Verdict: AUS-10 responds a touch faster on stones (less chromium).
Where the real difference shows up
On an 8″ Damascus-clad gyuto (same blade construction class):
| Example | Steel | Typical retail | Notes |
|---|---|---|---|
| Shun Classic / Premier | VG-MAX (VG-10 variant) | $160-$230 | Seki-made, pakkawood, widely distributed |
| Tojiro Flash | VG-10 core | $140-$200 | Seki-made, modest distribution |
| Miyabi Fusion | FC61 (VG-10 peer) | $200-$260 | Zwilling-owned, Seki-made |
| Okami Premium Damascus | AUS-10 core, 67-layer Damascus | $199 | DTC, Yangjiang-forged with Japanese steel |
| Enso HD | AUS-10A core | $190-$230 | Seki-made, pakkawood |
| Dalstrong Shogun X | AUS-10V core | $140-$200 | Chinese production with AUS-10 |
A VG-10 premium gyuto with Damascus cladding typically retails 15-25% higher than an AUS-10 peer of the same construction class. That delta is not the steel. It's brand positioning, region of forging, and distribution channel.
Which should you buy?
Buy AUS-10 Damascus.
98% of VG-10’s real-world performance at 50-60% of the retail. We’re the honest example of this category. Full AUS-10 Damascus case →
Shop the Okami Premium →Buy VG-10 instead if:
- Brand recognition matters (gift, peer signaling, prestige context).
- You want Williams Sonoma-tier retail distribution and return policies.
- You want a specific VG-10 product (Shun, Mac, Miyabi, Tojiro, etc.) and its aesthetic trumps the steel choice.
- You’re a sharpening enthusiast who will run controlled edge-retention tests and actually notices the small delta.
