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.
