What Is M390 Steel?
M390 is a high-alloy stainless powder metallurgy steel designed for exceptional wear resistance and edge retention. Its large amount of chromium and vanadium forms an abundance of extremely hard carbides throughout the steel.
These carbides dramatically slow edge wear during cutting, allowing knives made from M390 to remain sharp through prolonged use.
Typical composition includes approximately:
- Carbon: 1.9–2.2%
- Chromium: 20–21%
- Vanadium: 4%
- Molybdenum: 1%
- Tungsten: 0.6%
- Silicon and manganese in smaller amounts
The combination produces:
- Outstanding wear resistance
- Excellent corrosion resistance
- Very high hardness
- Long edge life
- Fine polished edges
Because of its extremely high carbide volume, M390 is more difficult to sharpen than many conventional stainless steels. Diamond or premium ceramic abrasives are usually recommended for efficient sharpening.
When properly heat treated, hardness generally falls between 60 and 62 HRC, although some makers may choose slightly different hardness levels depending on the intended use.

What Is Vanax Steel?
Vanax is also produced using powder metallurgy but follows a noticeably different metallurgical philosophy.
Instead of relying primarily on chromium carbides for wear resistance, Vanax uses a carefully balanced alloy containing nitrogen and vanadium to create very hard nitrides.
Nitrogen performs several important functions:
- Improves corrosion resistance
- Maintains high hardness
- Supports fine edge stability
- Reduces the need for excessive carbon
The result is an extremely clean microstructure with excellent resistance to rust while still providing premium cutting performance.
Typical composition includes approximately:
- Carbon: 0.36%
- Chromium: 18%
- Vanadium: 3.5%
- Molybdenum: 1.8%
- Nitrogen: 1.5%
Unlike traditional stainless steels, Vanax contains far less carbon than expected for a premium knife steel. The high nitrogen content compensates for this, allowing the steel to achieve impressive hardness while significantly improving corrosion resistance.
Knives are commonly hardened to 60–62 HRC, offering an excellent combination of edge retention, toughness, and stain resistance.

Chemical Composition Comparison
Although both steels belong to the premium stainless category, their alloy designs reveal very different engineering goals.
| Element | M390 | Vanax |
|---|---|---|
| Carbon | 1.9–2.2% | 0.36% |
| Chromium | 20–21% | 18% |
| Vanadium | 4% | 3.5% |
| Molybdenum | 1% | 1.8% |
| Nitrogen | — | 1.5% |
| Tungsten | 0.6% | — |
The biggest difference is immediately obvious:
M390 is carbon-rich.
Vanax is nitrogen-rich.
That single design choice influences nearly every aspect of their performance.
M390 develops a very high volume of chromium and vanadium carbides, which create extraordinary wear resistance but also increase sharpening difficulty.
Vanax forms hard vanadium nitrides instead of relying heavily on carbides. These nitrides provide impressive wear resistance while allowing the steel to remain cleaner and more corrosion resistant.
The reduced carbide volume also contributes to improved toughness and easier maintenance.
Powder Metallurgy Makes the Difference
Neither of these steels could achieve their impressive properties through conventional steelmaking.
Both are manufactured using powder metallurgy, a process in which molten steel is atomized into microscopic powder particles before being consolidated into solid billets.
This production method creates an extremely uniform distribution of carbides or nitrides throughout the steel.
Compared with conventionally cast steels, powder metallurgy provides several advantages:
- More uniform microstructure
- Smaller carbide particles
- Better toughness
- Improved grindability
- More consistent heat treatment
- Better overall cutting performance
Although both steels use powder metallurgy, the particles formed inside them differ significantly.
M390 develops an extremely dense population of hard carbides, maximizing wear resistance and edge life.
Vanax instead forms fine nitrogen-based nitrides, producing exceptional corrosion resistance without sacrificing premium cutting performance.
This difference in microstructure explains why these steels can feel surprisingly different during sharpening, heavy cutting, and long-term use—even when their hardness numbers are nearly identical.

Edge Retention Comparison
Edge retention is often the first characteristic people consider when choosing a premium knife steel. Both M390 and Vanax perform at a very high level, but they achieve their cutting longevity through different metallurgical mechanisms.
M390 has long been recognized for its outstanding wear resistance. The steel contains a very high volume of extremely hard chromium and vanadium carbides that resist abrasion during cutting. As a result, the edge wears away very slowly, especially when slicing abrasive materials such as cardboard, rope, leather, or fibrous food.
Vanax also offers excellent edge retention, but it approaches the problem differently. Instead of relying primarily on carbide volume, it uses hard vanadium nitrides combined with a refined powder metallurgy microstructure. While its wear resistance is slightly lower than M390, many users report that Vanax maintains a remarkably consistent cutting feel over extended use.
In practical kitchen work, the difference is often much smaller than laboratory wear tests suggest. Both steels can complete many food preparation tasks before noticeable dulling occurs.
For users whose priority is maximum cutting longevity between sharpening sessions, M390 generally holds a slight advantage.
Edge Retention Rating
| Steel | Rating |
|---|---|
| M390 | ★★★★★ |
| Vanax | ★★★★☆ |
Winner: M390
Toughness Comparison
Toughness describes a steel’s ability to resist chipping, cracking, or breaking when subjected to impact or lateral stress.
Many people assume that harder steels are automatically more brittle, but modern powder metallurgy allows both steels to maintain impressive toughness despite their high hardness.
M390 performs well for a wear-resistant stainless steel, yet its extremely high carbide content naturally reduces toughness compared with steels designed specifically for impact resistance.
Vanax benefits from a cleaner microstructure and lower carbide volume. The presence of nitrogen-based nitrides allows it to maintain excellent cutting performance while improving resistance to edge chipping.
This difference becomes more noticeable during demanding tasks such as:
- Cutting dense vegetables
- Processing meat around joints
- Outdoor camp food preparation
- Occasional contact with harder materials
The advantage is not dramatic, but Vanax generally tolerates unexpected stress better than M390.
Users who occasionally twist the blade or encounter harder cutting media may appreciate the additional safety margin.
Toughness Rating
| Steel | Rating |

Winner: Vanax
Corrosion Resistance
Corrosion resistance is where these steels begin to separate significantly.
M390 is already considered one of the most corrosion-resistant premium knife steels available. Its chromium content of approximately 20% provides excellent protection against staining and rust when the knife receives ordinary care.
For most users, M390 performs exceptionally well in:
- Home kitchens
- Professional kitchens
- Outdoor cooking
- General everyday carry
- Moderate humidity
However, Vanax takes corrosion resistance to another level.
Its unique nitrogen-rich alloy design greatly reduces the formation of chromium carbides, leaving more chromium available to protect the steel against oxidation. Combined with nitrogen, this results in corrosion resistance that exceeds most conventional stainless knife steels.
Vanax performs exceptionally well in:
- Coastal environments
- Saltwater exposure
- Commercial kitchens
- Fishing
- Marine use
- Tropical climates
- High-humidity storage
For users who regularly work near saltwater or frequently prepare acidic foods, Vanax offers one of the best corrosion-resistant solutions currently available.

| Vanax | ★★★★★+ |
Winner: Vanax
Sharpening Difficulty
Premium performance usually comes with more demanding sharpening, and both steels require quality sharpening equipment.
M390’s exceptional wear resistance also makes it one of the more difficult stainless steels to sharpen. The hard vanadium carbides resist abrasion from conventional sharpening stones.
Diamond plates or high-quality ceramic abrasives significantly reduce sharpening time and improve consistency.
Vanax remains a premium steel, but many sharpeners find it somewhat easier to sharpen than M390.
The cleaner microstructure allows fresh abrasive particles to engage the edge more efficiently, resulting in faster burr formation and simpler refinement.
Neither steel should be considered easy to sharpen compared with entry-level stainless steels, but Vanax generally requires less effort.

Microstructure Differences
The microscopic structure of a steel has a tremendous influence on how it behaves during cutting.
Although both steels are produced using powder metallurgy, their internal structures differ considerably.
M390 Microstructure
M390 contains:
- High chromium carbide content
- High vanadium carbide content
- Dense wear-resistant particles
- Extremely abrasion-resistant cutting edge
This structure maximizes edge retention but also increases sharpening difficulty and slightly reduces toughness.
Vanax Microstructure
Vanax contains:
- Fine vanadium nitrides
- Nitrogen-strengthened matrix
- Lower carbide volume
- Cleaner overall grain structure
Because nitrides occupy less volume than large carbide networks, the cutting edge experiences more uniform support. This contributes to better toughness while maintaining excellent wear resistance.
Many experienced sharpeners also describe Vanax as producing a smoother, more refined edge during polishing.
Real-World Cutting Performance
Laboratory testing is useful, but daily cutting performance is what matters most.
For cardboard, rope, heavy packaging, and other abrasive materials, M390 typically retains its aggressive slicing ability longer.
Users who sharpen infrequently often appreciate this characteristic because the knife continues cutting efficiently even after extended use.
Vanax excels in a different way.
Rather than maximizing wear resistance alone, it offers a balanced combination of:
- Excellent edge retention
- Outstanding corrosion resistance
- Very good toughness
- Consistent edge stability
Many users notice that Vanax continues to feel exceptionally smooth during food preparation even after prolonged use.
Its cutting performance is often described as predictable and refined rather than purely wear resistant.

Wear Resistance
Wear resistance is one of the defining characteristics of premium knife steels, and it determines how well a blade resists gradual edge loss from abrasion during cutting.
Materials such as cardboard, rope, dense vegetables, leather, and certain synthetic fibers slowly wear away the cutting edge. The more wear-resistant the steel, the longer the knife continues slicing efficiently before sharpening becomes necessary.
This is where M390 has built its outstanding reputation.
Its combination of high carbon, high chromium, and approximately 4% vanadium produces an extremely dense network of very hard carbides. These microscopic carbides act like tiny wear-resistant particles embedded throughout the edge, significantly slowing material loss.
Vanax also performs extremely well, but its design philosophy is different.
Rather than maximizing carbide volume, Vanax relies on vanadium nitrides combined with nitrogen strengthening. This creates excellent wear resistance while preserving better toughness and corrosion resistance.
In everyday kitchen use, many users may never notice a dramatic difference between the two steels.
However, during continuous cutting of abrasive materials, M390 generally maintains its sharpness for a longer period.
Wear Resistance Rating
| Steel | Rating |
|---|---|
| M390 | ★★★★★ |
| Vanax | ★★★★☆ |
Winner: M390
Edge Stability
Edge retention and edge stability are often confused, but they describe different characteristics.
- Edge retention measures how long the edge remains sharp.
- Edge stability describes how well a very thin edge resists rolling or micro-chipping during use.
A knife with excellent edge stability can support thinner edge geometry while maintaining reliable cutting performance.
M390 performs extremely well with thin edges, especially for slicing applications. Its high hardness allows very acute edge angles that cut effortlessly.
However, because of its higher carbide volume, extremely thin edges may become slightly more susceptible to micro-chipping if used improperly.
Vanax benefits from its cleaner microstructure and lower carbide volume.
Its fine nitrides provide outstanding support for thin edges while improving resistance to microscopic damage.
This characteristic is especially appreciated by users who sharpen at low edge angles for maximum slicing performance.
Edge Stability Rating
| Steel | Rating |
