VG-10 Steel: Is It Good? Composition, HRC and Equivalents
VG-10 is a cutlery-grade Japanese stainless steel made by Takefu Special Steel, built around roughly 1% carbon and 15% chromium with cobalt, molybdenum and vanadium added. Hardened to 60-61 HRC, it takes a very keen edge and resists rust well, but it chips more readily than softer steels.
Is VG-10 Steel Good?
Yes, for kitchen knives specifically. VG-10 sits in a useful spot: hard enough to hold a fine edge through weeks of board work, stainless enough that a home cook will not ruin it by leaving it wet for ten minutes, and fine-grained enough to sharpen back to keen without specialist kit.
It has been the default premium Japanese stainless for two decades, which is why it appears in so many knives and why so many people have an opinion about it. The criticism you will find on knife forums is real but narrow: at the very acute edge angles Japanese knives are ground to, VG-10 tends to chip rather than roll. That is a consequence of its hardness, not a manufacturing fault, and it matters mostly to people who take an edge below about 15 degrees per side.
For a home kitchen it is a strong steel. For a professional line cook working frozen edges and bone, a slightly softer, tougher steel is the safer choice.
VG-10 Steel Composition
The published spec for VG-10 - "V Gold 10", from Takefu Special Steel in Fukui, Japan - is consistent across suppliers:
| Element | Approx. % | What it does |
|---|---|---|
| Carbon | 1.0 | Hardness and edge retention |
| Chromium | 15.0 | Corrosion resistance; above ~13% makes it stainless |
| Cobalt | 1.5 | Tempering resistance and fine grain |
| Molybdenum | 1.0 | Strength and wear resistance |
| Vanadium | 0.2 | Grain refinement, carbide formation |
The cobalt is the distinguishing element. Plenty of stainless steels hit 1% carbon and 15% chromium; the cobalt addition is what lets VG-10 be hardened well past 60 HRC without becoming brittle, and it is why the steel has a reputation for taking a genuinely fine edge.
VG-10 Steel Hardness
Most makers finish VG-10 at 60-61 HRC, with some running to 62. That is firmly in the hard-kitchen-steel band: harder than a European chef knife at 56-58, softer than a powder steel like SG2 at 63-64.
What 60-61 HRC means in practice is that the edge holds through a lot of work before it needs a stone, and that you should not use the knife as a lever. If you want the full picture of what these numbers mean, our Rockwell hardness scale guide breaks down the chart number by number.
What Is VG-10 Comparable To?
This is the most common VG-10 question, and the honest answer is that it has several close relatives.
VG-10 vs 440C
The closest Western analogue. 440C runs about 1% carbon and 17% chromium with no cobalt. VG-10 is widely described as a Japanese answer to 440C with cobalt added for tempering resistance. In use, VG-10 typically takes a finer edge and holds it slightly better; 440C is a little tougher and usually cheaper.
VG-10 vs AUS-10
Very similar carbon, less chromium in AUS-10 (around 13-14% against VG-10's 15%) and no cobalt. Both land at similar hardness and both are used as Damascus cores. AUS-10 is the core steel in our Feather Forge line; we cover it in detail in the AUS-10 steel guide, including the direct AUS-10-versus-VG-10 comparison.
VG-10 vs 10Cr15CoMoV
Read the name and you can see the family resemblance: roughly 1% carbon, 15% chromium, cobalt, molybdenum, vanadium. On paper 10Cr15CoMoV is the closest thing to VG-10 in the market, and it is the core steel behind our Silver Dynasty and Damascus Dynasty blades. The 10Cr15CoMoV guide puts the two side by side.
VG-10 vs D2
Not really comparable, despite the frequency of the question. D2 is a semi-stainless tool steel at around 12% chromium - it wears better and holds a working edge longer, but it will develop rust spots in a kitchen and it is noticeably harder to sharpen. For food prep, VG-10 is the better choice; for a hard-use outdoor blade, D2 has the advantage.
VG-10 vs SG2 / Super Gold 2
Same manufacturer, different league. SG2 is a powder metallurgy steel that runs harder and holds an edge considerably longer, at a higher price and with a steeper sharpening learning curve. VG-10 is the more forgiving of the two.
Why VG-10 Is Almost Always a Core, Not a Whole Blade
If you have seen VG-10 advertised, you have almost certainly seen it described as a core: "67-layer Damascus with a VG-10 core", or "San Mai VG-10". That is not marketing decoration, it is the sensible way to use a hard steel.
A blade made entirely of 61 HRC steel is stiff and brittle. Forge-weld softer, tougher steel around a hard cutting core and you get the best of both: the core carries the edge, the cladding absorbs the shock and flex. San Mai is the three-layer version of this; Damascus cladding is the many-layer version, and the pattern is a by-product of the layering rather than the point of it.
Our own blades use the same principle with different core steels. The Feather Forge line wraps 73 layers of feather Damascus around an AUS-10 core. The Dynasty blades use a cobalt-bearing high-carbon core at 60 HRC. The Bara Forge 9" Gyuto runs a 10Cr17MoV core in layered forged steel. If you want the full explanation of how the layers work, the Damascus steel guide covers it, and San Mai steel explained covers the three-layer version.
The Catch: VG-10 and Chipping
Worth stating plainly, because it is the single most common complaint about the steel. VG-10 at 60-61 HRC, ground to a thin Japanese edge, will micro-chip if you twist it in a squash, cut on glass or ceramic, or hit a chicken bone. It does not bend and recover the way a softer European blade does - it breaks small pieces off the apex instead.
Three habits prevent almost all of it: cut on wood or soft composite, never bone or frozen food; slice, do not scrape or lever; and hone regularly so you are never forcing a dull edge. Do those and the chipping question largely disappears.
Is VG-10 Stainless? Rust and Care
Yes. At 15% chromium VG-10 is comfortably stainless, and it is one of the more corrosion-resistant kitchen steels in common use. That does not make it rustproof - no high-carbon stainless is. Acidic food left on the blade, or a night in the sink, will still mark it.
Hand wash and dry immediately, never put it in a dishwasher, and store it on a magnetic strip or in a sheath rather than loose in a drawer. Our knife care guide covers the routine in full.
Sharpening VG-10
VG-10 sharpens well but takes patience. It is harder than the Western steels most people learn on, so expect to spend longer on the stone and to use less pressure - leaning on a hard steel is how you round the apex rather than cut it. A 1000-grit stone for setting the bevel and a 3000-6000 finishing stone will bring it back to shaving sharp.
Avoid pull-through sharpeners entirely. They tear at a hard fine-grained steel and undo exactly the edge quality you paid for. The whetstone guide walks through the whole process step by step.
What We Use, and Why We Are Telling You
The Cooking Guild does not build on VG-10. Our cores are AUS-10 in the Feather Forge line, a cobalt-bearing high-carbon core in Silver Dynasty and Damascus Dynasty at 60 HRC, 10Cr17MoV in Bara Forge, SLD tool steel in the San Mai Kaiju line, 7Cr17MoV in Torii, and 1080 high carbon in the Snazan Heritage Cleaver.
That is worth saying out loud in a guide about VG-10, because almost every other page you will find on this steel is published by somebody selling it. We are not. VG-10 is a good steel and we would not argue otherwise - it simply sits on the same part of the curve as several alternatives, and which one ends up in your hand matters far less than the heat treatment, the grind and the geometry behind it.
Every blade we make is hand sharpened and oiled before it ships, and comes with a 99-day home trial and a free lifetime guarantee. They are the sharpest blades you will ever use or your money back - and the only way to test that claim is to cook with one.
Frequently Asked Questions
Is VG-10 a high-end steel?
It is upper-mid. VG-10 is a genuine premium stainless and was the top of the kitchen market for years, but powder steels like SG2 and modern alloys have since moved above it. Treat it as a very good steel rather than a top-tier one.
What is VG-10 equivalent to?
Closest matches are 10Cr15CoMoV on composition, 440C as the Western analogue, and AUS-10 as the nearest common Japanese alternative. None is an exact substitute, but all four land in the same performance band.
What HRC is VG-10?
Typically 60-61 HRC, occasionally finished to 62. Harder than a standard European chef knife at 56-58, softer than a powder steel at 63-64.
Does VG-10 rust?
Rarely, but it can. At 15% chromium it is well protected, yet it is still a high-carbon stainless. Dry it after washing and it will not give you trouble.
