The Gold Standard of Stainless Japanese Knife Steels
Developed by Takefu Special Steel in the 1960s. Three decades later, still the steel every mid-premium Japanese production knife is measured against.
VG-10 is the best-all-round stainless steel for Japanese kitchen knives — but it’s not the only good answer.
VG-10 hits the sweet spot of hardness (60–62 HRC), edge retention, corrosion resistance, and sharpen-ability. It’s what Shun, Mac, Tojiro, and hundreds of mid-premium Japanese brands use. Okami uses AUS-10 instead — the reasoning is below.
What VG-10 actually is
VG-10 is a high-carbon, high-chromium stainless steel developed by Takefu Special Steel Co., Ltd. in Echizen, Fukui Prefecture. The designation “VG” stands for “V Gold,” and the 10 refers to its position in Takefu’s V-series product line.
It was originally engineered for premium pocket knives and later adopted aggressively by Japanese kitchen-knife makers in Seki in the 1990s. Today, it’s arguably the most widely used premium Japanese stainless steel in the world kitchen market.
The critical properties that make VG-10 successful:
- Hardens to 60–62 HRC — hard enough to hold a fine edge, soft enough not to chip catastrophically.
- Genuinely stainless — no special drying required after washing, no patina, no reactivity with acidic foods like tomato or lemon.
- Takes a mirror polish — the fine grain structure allows both hair-popping sharpness and elegant finishing.
- Sharpens predictably on waterstones — grabs the stone, builds a burr, comes to an edge without excessive work.
What’s in it
VG-10’s composition (by weight, approximate — Takefu publishes narrow tolerances rather than exact values):
| Element | Range (%) | What it does |
|---|---|---|
| Carbon (C) | 0.95–1.05 | The primary hardener. Enables high HRC when heat-treated. |
| Chromium (Cr) | 14.5–15.5 | Corrosion resistance. Above ~13%, the steel is considered “stainless.” |
| Molybdenum (Mo) | 0.9–1.2 | Improves edge retention and toughness. Suppresses carbide grouping. |
| Vanadium (V) | 0.1–0.3 | Forms hard vanadium carbides that boost wear resistance. |
| Cobalt (Co) | 1.3–1.7 | The defining addition. Lets the steel harden without losing toughness. |
| Manganese (Mn) | ≤0.5 | Deoxidizer, minor hardness contribution. |
The cobalt addition is VG-10’s signature. Cobalt allows the steel to be hardened to 60+ HRC without becoming glass-brittle, and it refines the carbide structure so the edge stays cleaner under microscopy. Steel snobs call it “the steel that made stainless credible in serious kitchens.”
What VG-10 feels like in the hand
Out of the box
A quality VG-10 knife should pass the paper-cut test straight from the factory — slicing cleanly through printer paper without tearing. Our own comparison testing puts Shun Classic VG-MAX (a minor VG-10 variant) and Tojiro DP VG-10 in almost identical territory: 58g pull force on a 4mm-wide onion slice, give or take 4g.
Edge retention
With normal home-kitchen use — daily cutting, wooden or HDPE board, honed on a ceramic rod before each session — a VG-10 edge holds its paper-cut standard for 3–6 months before noticeable degradation. That’s roughly double what you’d expect from a softer Western chef’s knife (54–57 HRC) in the same conditions.
Sharpening
VG-10 is moderately friendly on waterstones. It cuts against a 1000-grit synthetic stone without excessive dishing, builds a clean burr within a dozen strokes, and polishes well at 5000–8000 grit. It is noticeably harder to sharpen than AUS-8 or German X50CrMoV15, but measurably easier than powder steels like SG2 or R2.
Weakness: chipping
VG-10’s hardness comes with fragility at very thin edges. Tips break if you twist them. Blades chip against bones, frozen food, or glass/ceramic boards. None of this is unique to VG-10 — every 60+ HRC steel shares it — but it’s worth saying: VG-10 is not a steel to abuse.
Why Okami uses AUS-10, not VG-10
We get this question a lot, and we want to answer it honestly. VG-10 is an excellent steel. So is AUS-10. For a mid-premium kitchen knife, the differences are subtle:
| Property | VG-10 | AUS-10 |
|---|---|---|
| Carbon content | ~1.0% | ~1.1% |
| Chromium | 14.5–15.5% | 13–14.5% |
| Cobalt | 1.3–1.7% | None |
| Typical HRC | 60–62 | 60–61 |
| Edge retention | Excellent | Excellent (slightly behind VG-10 in most tests) |
| Toughness | Good | Marginally better |
| Sharpen-ability | Moderate | Marginally easier |
| Stain resistance | Genuinely stainless | Stainless |
| Origin | Takefu Special Steel (Japan) | Aichi Steel (Japan) |
| Typical retail markup | 20–30% price premium | Lower-cost sourcing, direct to maker |
In head-to-head blind testing, most cooks cannot tell the difference in the first six months of use. VG-10 has a slight edge-retention advantage; AUS-10 is marginally easier to bring back to sharp on a whetstone. Both hit 60–61 HRC, both are genuinely stainless, both take a 15° edge cleanly.
We chose AUS-10 because it delivered 98% of VG-10’s real-world performance at a sourcing cost that let us sell our Premium Damascus for $199 — against VG-10 peers that retail for $300–400 with the same construction. We think that’s the right trade for a mid-premium kitchen knife buyer. The full AUS-10 case →
VG-10 vs. other kitchen steels
| Steel | Type | HRC | Positioning |
|---|---|---|---|
| VG-10 | Stainless | 60–62 | The mid-premium standard |
| AUS-8 | Stainless | 58–60 | Entry-level Japanese stainless |
| AUS-10 | Stainless | 60–61 | Direct VG-10 peer |
| SG2 / R2 | Powder | 62–64 | A tier above VG-10 in edge retention, harder to sharpen |
| Shirogami #2 (White) | Carbon | 62–64 | Traditional; the purists’ choice; requires care |
| Aogami Super (Blue) | Carbon | 63–65 | Top-tier traditional; exceptional edge, reactive |
| X50CrMoV15 (Wusthof, Henckels) | Stainless | 54–57 | Softer European steel; tougher but loses edges faster |
How to keep a VG-10 edge
VG-10 is easy to live with. Three rules:
- Hand-wash only, even though it’s stainless. Dishwasher heat and detergent dull the edge and can warp the handle. Rinse with mild soap, dry with a towel, put away.
- Hone with a ceramic rod, not a steel one. Traditional steel honing rods are softer than VG-10 and can’t realign the edge. Ceramic works; fine diamond rods also work.
- Resharpen every 2–6 months on a 1000/6000 waterstone. That’s the rhythm for normal home use. High-volume cooks will do it monthly.
