Japan's workhorse benchmark, the steel that defined a generation of kitchen knives.
VG-10
For the Newcomer
VG-10 is the most widely used premium Japanese stainless steel in the world. If you have bought a Japanese kitchen knife in the $100 to $300 range, there is a good chance it is VG-10. It holds a significantly sharper, longer-lasting edge than German kitchen steels at a hardness level that still survives real kitchen use. The tradeoff versus German steel is twofold: it chips at the edge under abuse rather than bending, and it takes more skill to sharpen properly. In the hands of a careful cook it is excellent; in the hands of someone who abuses knives it will frustrate.
About this composition
Cobalt's actual purpose. The cobalt in VG-10 is not primarily for edge retention or toughness. As Larrin Thomas puts it, "the cobalt was likely added to increase tempering resistance so that VG10 can be used with coatings that must be applied at high temperatures." For a kitchen knife that never sees coating temperatures, cobalt's contribution is largely theoretical, and it actively reduces toughness in nearly every study Thomas examined.
Carbide structure. Primarily chromium Microscopic hard particles within steel that resist wear. Their type and size shape how an edge wears and how fine it can get.. At 12 to 16% carbide volume, no measurable vanadium carbide forms (the vanadium is too low), so the edge wears by losing chromium carbides: competent, but not in the vanadium-carbide tier of Elmax or S35VN.
Performance Deep Dive
Edge retention: Very good for a stainless steel.
A genuine step above German X50CrMoV15 / 4116 and AUS-8. A standardized industry test that measures how much material a blade can slice before going dull; the standard edge-retention benchmark. testing places it above 440C and below S35VN and Elmax. It holds a working edge noticeably longer between sharpenings than a standard German knife.
Toughness: Moderate.
5.8 ft-lbs average at about 60.7 Rockwell C, the standard hardness scale for blade steel. Most kitchen knives fall between about 56 and 66. (Larrin Thomas Charpy testing). It chips rather than rolls, particularly at edge angles below about 14 degrees per side and under hard impacts. The reputation for chipping is real but often exaggerated; much of it stems from poor heat treatment by certain manufacturers or from use at overly acute angles.
Corrosion resistance: Very good.
15% chromium handles daily kitchen exposure, acidic foods, and humidity without issue, with no corrosion in four days of distilled-water spray (Larrin Thomas). It is not suited to saltwater or prolonged acid contact.
Ease of sharpening: Moderate, with deburring as the catch.
It sharpens to very high sharpness on 1000 to 3000 grit stones, but VG-10 is notorious for retaining a A thin sliver of steel that folds over the edge during sharpening. If not removed, it feels sharp but collapses within a meal, leaving a dull edge.. The standard "chase and flip the burr" technique does not work reliably here: the burr must be cut off with very light, near-longitudinal strokes at a high angle, or with a micro-bevel. Skip this step and you are left with a false edge that feels sharp but fails within a meal. Full technique is in the care section.
- vs. AUS-10: VG-10 holds an edge about 25 to 40% longer; AUS-10 is tougher, less chippy, and easier to sharpen.
- vs. AUS-8: VG-10 has clearly better edge retention; AUS-8 is more forgiving and significantly easier to sharpen.
- vs. SG2 / R2: SG2 holds an edge 1.5 to 2x longer; VG-10 is easier to sharpen and more accessible.
- vs. VG-MAX: functionally nearly identical in practice at the same 60 to 61 HRC target.
- vs. N690: edge retention is essentially identical; N690 has better corrosion resistance.
In the Kitchen
VG-10 is the entry point into Japanese kitchen knife performance for good reason: for $100 to $300 you can get a knife that meaningfully outperforms German production stainless on every metric except toughness. Pair it with gyutos, santokus, nakiris, and petties, and buy from a Japanese maker with documented heat treatment (Takamura, Kato, Hattori, Tojiro). Avoid no-name listings, since VG-10 is the most-faked steel designation in the knife world. And master the deburring step early; the rest of the sharpening is the easy part.
Composition
| Element | % | Role |
|---|---|---|
| Carbon (C) | 1 | Hardness and carbide formation |
| Chromium (Cr) | 15 | Corrosion resistance; primary carbide former |
| Molybdenum (Mo) | 1 | Hardenability, corrosion resistance |
| Vanadium (V) | 0.25 | Minor wear resistance contribution |
| Cobalt (Co) | 1.55 | Tempering resistance (for high-temp coating processes, not kitchen relevance) |
| Manganese (Mn) | 0.5 | Structural (max 0.5%) |
| Silicon (Si) | 0.5 | Structural (max 0.5%) |
Steel family: Conventional ingot stainless from Takefu Special Steel (Echizen/Takefu region, Fukui Prefecture). Available to any knifemaker worldwide. The name derives from the Japanese 金 (kin/gold): "V Gold 10". Cobalt's purpose here is tempering resistance for high-temperature coating processes, not edge retention or toughness.
