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.

60–62 HRC
VG-10 Hardness
60–61 HRC
AUS-10 Hardness
Takefu
VG-10 Mill
Aichi Steel
AUS-10 Mill
The quick answer

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.

01 · Chemistry

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.

02 · Real-world testing

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).
03 · The retail markup gap

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.

04 · Our recommendation

Which should you buy?

If honest value matters more than brand name

Buy AUS-10 Damascus.

Our Premium Damascus: $199 · AUS-10 core · 67-layer 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.
