The Gold Standard of Stainless Japanese Knife Steels

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):

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. In our experience, Shun Classic VG-MAX (a close VG-10 derivative) and Tojiro DP VG-10 land in nearly identical territory out of the box: both slice cleanly with minimal pressure, and neither holds a meaningful factory-edge advantage.

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.

Performance ratings at a glance

These ratings are Okami estimates on a 1-10 scale spanning the full range of kitchen knife steels. Methodology: we synthesize Takefu’s published composition, typical production hardness, and independent metallurgy test data for VG-10 and comparable steels, then sanity-check the result against our own sharpening and kitchen experience.

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:

In practice, 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 →

We also keep a dedicated head-to-head comparison at VG-10 vs AUS-10 if you want the property-by-property breakdown.

VG-10 vs. other kitchen steels

VG-10 vs SG2 / R2

SG2 (also sold as R2) is Takefu’s powder-metallurgy steel: finer grain, more vanadium, and hardness of 62-64 HRC. It holds a working edge noticeably longer than VG-10 but costs more, takes longer on the stones, and is less forgiving of rough handling. VG-10 remains the better value for most home cooks; SG2 rewards people who already sharpen well and want maximum time between sessions.

VG-10 vs AUS-8

AUS-8 sits a clear tier below: roughly 0.75% carbon, no cobalt, 58-60 HRC. VG-10 holds its edge longer and takes a finer polish; AUS-8 is tougher, cheaper, and faster to resharpen. If you are buying a first Japanese knife and expect to learn sharpening on it, AUS-8 is the more forgiving teacher. If you already maintain your knives, VG-10 is worth the step up.

VG-10 vs VG-MAX

VG-MAX is a proprietary Takefu derivative made for Kai, with small adjustments to carbon, chromium, vanadium, and added tungsten. In practice the two behave almost identically: same hardness window, same sharpening feel, same stainless behavior. Treat Shun’s VG-MAX marketing as “VG-10, lightly tuned,” not as a different class of steel.

How to keep a VG-10 edge

VG-10 is easy to live with. Three rules:

1. 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.
2. 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.
3. 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.

Heat treatment, where VG-10 knives are won or lost

Steel leaves Takefu as flat stock. Everything that makes it a good or bad knife happens afterward, in the maker’s hardening line. In plain language, the process runs like this:

1. Austenitizing. The blade is heated to roughly 1050-1080°C so carbon and alloying elements dissolve into the iron matrix. Too cool or too brief, and the steel never reaches full hardness. Too hot, and the grain coarsens, which makes the finished edge chip-prone.
2. Quenching. Rapid cooling locks the structure into hard martensite. Many makers add a sub-zero (cryogenic) step, which converts leftover soft austenite and typically buys an extra point of hardness.
3. Tempering. One or two low-temperature cycles around 150-200°C trade a little hardness for a lot of stability. This is what stops a hard blade from behaving like glass.

Done well, VG-10 lands at approximately 59-62 HRC, with most good kitchen knives at 60-61. Done poorly, the same steel can leave the factory soft enough to roll on a carrot or brittle enough to chip on a scallion. This is why two “VG-10” knives at the same price can behave like different materials, and why we keep repeating the same point across this site: the maker matters more than the steel. A well-treated AUS-10 or AUS-8 blade will outperform a badly treated VG-10 blade every single day.

Which brands and makers actually use VG-10

Because Takefu sells VG-10 openly, it shows up across hundreds of brands. These are makers we have researched and profiled ourselves, with notes on exactly where the steel appears:

• Tojiro: the DP series is the reference budget VG-10 knife, a genuine VG-10 core in stainless cladding at a price nobody else has matched for decades.
• Shun, with an asterisk: Shun Classic ran VG-10 for years, then moved to VG-MAX, the proprietary Takefu derivative described above. Same steel family, near-identical behavior.
• Kasumi: Sumikama’s Kasumi Damascus line is built on a VG-10 core under Damascus cladding, ground in Seki.
• Mcusta Zanmai and parent Mcusta: the Zanmai Classic and Damascus kitchen lines use VG-10 cores, and many Mcusta folding knives carry VG-10 blades as well.
• Sakai Takayuki: the 33-layer and 45-layer Damascus gyutos that introduced many Western cooks to Sakai are VG-10 core.
• Enso: the HD series, made by Yaxell in Seki, is VG-10 under hammered Damascus cladding. Yaxell’s own Ran line is VG-10 too.
• Kikuichi, with a caveat: Kikuichi is best known for its Swedish stainless and carbon steel lines, so do not assume VG-10 there. Only select parts of the catalog use it; check the specific series.

A useful pattern to notice: most production VG-10 kitchen knives come out of Seki, where factories buy pre-laminated VG-10 blanks from Takefu, then grind, heat treat, and finish them locally. The steel is the shared ingredient; the grinding and hardening are where brands genuinely differ.

Takefu Special Steel and the Echizen connection

VG-10 comes from Takefu Special Steel Co., Ltd. (武生特殊鋼材), based in Echizen City, Fukui Prefecture. The company grew up inside one of Japan’s oldest blade regions: Echizen has forged knives and farm tools for roughly 700 years, and Takefu began as a specialty steel supplier to those local smiths before its alloys went national.

The “V Gold” series is Takefu’s family of cutlery stainless steels. VG-1 and VG-2 came first; VG-10, with its signature cobalt addition, became the flagship. Takefu later developed VG-MAX for Kai and the powder-metallurgy SG2 that now defines the tier above. As a kitchen-knife steel, VG-10’s rise dates to the 1990s, when Seki’s production houses adopted it at scale and exports carried it worldwide.

One under-appreciated part of Takefu’s business: it does not just sell bar stock. It supplies pre-laminated billets, VG-10 cores already clad in stainless or patterned suminagashi layers, to workshops in Echizen, Seki, and Sakai. That clad-blank supply chain is a big reason so many mid-premium Damascus knives from different brands feel closely related: many literally start from the same material.

Sharpening VG-10: angles, grits, and burr behavior

Angles

15 degrees per side is the sensible default and matches most factory edges. Practiced sharpeners can take a thin gyuto to 12-13 degrees per side for noticeably better food release and fall-through, but below that the edge starts trading stability for sharpness. If the knife sees board contact all day, stay at 15.

Stones and grits

A 1000-grit synthetic waterstone does 90% of the work on VG-10. Drop to 320-500 grit only for chip repair or reprofiling. Finish at 3000-6000 grit for a kitchen edge that both bites and glides; an 8000-grit polish is optional and mostly cosmetic for produce work, though it does help with fine slicing. VG-10 does not need diamond stones; ordinary aluminum-oxide synthetics cut it fine.

Burr behavior

VG-10 raises a clear, detectable burr within a dozen strokes, which makes progress easy to track. The burr is slightly tenacious: it likes to flip from side to side rather than shear off. Remove it with progressively lighter alternating strokes, then two or three featherweight edge-leading passes at a marginally raised angle. If a paper test snags in one spot, the burr is still hanging on there.

Stropping and honing

Three to five light passes per side on bare leather, or leather with 1-micron compound, cleans up the last of the burr. Keep strop sessions short: over-stropping at inconsistent angles rounds the apex. Between sharpenings, a ceramic honing rod once or twice a week keeps the edge aligned; skip traditional grooved steel rods, which are too soft for 60+ HRC blades.

Myths and misconceptions about VG-10

“VG-10 is brittle and chips constantly”

Partly earned, mostly overstated. The chipping stories cluster around three causes: very thin factory edges meeting hard boards, occasional over-hardened batches from less careful factories, and cooks arriving from soft German knives with habits (twisting, scraping, bone contact) that no 60+ HRC steel tolerates. Well-treated VG-10 at 60-61 HRC behind a 15-degree bevel is not fragile by Japanese-knife standards. It is simply not a soft steel, and it does not pretend to be.

“Powder steels made VG-10 obsolete”

SG2 and its peers do hold an edge longer. They also cost more, sharpen slower, and punish sloppy stone work. VG-10 still occupies the equilibrium point of price, edge retention, and maintainability, which is exactly why production brands keep choosing it thirty years on.

“All VG-10 knives perform the same”

The steel sets a ceiling; heat treatment and geometry decide how close a knife gets to it. A $70 Tojiro DP and a $250 Damascus gyuto may share core steel while cutting very differently, because grind thickness behind the edge matters more than the label on the box.

“The Damascus layers make it sharper”

The patterned cladding on VG-10 Damascus knives is cosmetic and protective. Only the VG-10 core ever touches the food. A plain-clad VG-10 blade with the same grind cuts identically to a 67-layer one.

VG-10 frequently asked questions

Is VG-10 good knife steel?

Yes. For kitchen knives it is arguably the best-balanced mainstream stainless: approximately 60-62 HRC, genuinely rust-resistant, fine-grained enough for a very keen edge, and sharpenable on ordinary waterstones. It has been the mid-premium benchmark since the 1990s.

What HRC is VG-10?

Typically 60-62 HRC in kitchen knives, with most quality production landing at 60-61. The exact number depends on each maker’s heat treatment, not on Takefu.

Does VG-10 rust?

Not under normal kitchen conditions. With roughly 15% chromium it is genuinely stainless: wash, dry, done. Prolonged contact with salt water or acidic residue can still cause spotting, so do not leave it wet overnight or in a dishwasher.

Is VG-10 hard to sharpen?

Moderately easy. It is noticeably slower on stones than AUS-8 or soft German steel, but far quicker than powder steels. A 1000/6000 waterstone combination handles it comfortably, and the burr is easy to detect.

VG-10 vs SG2: which is better?

SG2 holds an edge longer and reaches 62-64 HRC; VG-10 is tougher relative to its price, cheaper, and easier to sharpen. SG2 suits confident sharpeners chasing maximum edge life. VG-10 suits nearly everyone else.

Is Shun made of VG-10?

Current Shun Classic knives use VG-MAX, a proprietary Takefu derivative of VG-10 with minor composition tweaks. Earlier Shun Classics used VG-10 itself. In hand, the two are near-identical.

Is VG-10 better than AUS-8?

It holds an edge longer and polishes finer, thanks to higher carbon plus cobalt and a 60-62 HRC window. AUS-8 counters with better toughness, lower price, and faster sharpening. Better depends on whether you value edge life or forgiveness.

Who makes VG-10?

Takefu Special Steel Co., Ltd. of Echizen City, Fukui Prefecture, Japan. Knife brands do not make VG-10; they buy it from Takefu, often as pre-laminated blanks, and do their own grinding and heat treatment.
