S35VN Steel Review
An Independent Guide
Introduction
CPM S35VN has been one of the most respected premium knife steels for over a decade. Developed as an improvement over CPM S30V, S35VN was designed to provide a better balance of toughness, edge retention, corrosion resistance, and sharpen ability.
Since its introduction, CPM S35VN has become a favorite among knife manufacturers, custom makers, outdoor enthusiasts, and everyday carry (EDC) users. It has been used in thousands of knife models ranging from folding knives and fixed blades to hunting knives and premium kitchen knives.
However, with the arrival of newer steels such as MagnaCut, CPM S45VN, and various high-performance powder metallurgy steels, many knife enthusiasts wonder whether S35VN is still relevant today.
In this comprehensive CPM S35VN steel review, we’ll examine its composition, properties, hardness, edge retention, corrosion resistance, toughness, sharpening characteristics, and how it compares to popular alternatives like MagnaCut, S30V, S45VN, M390, and ELMAX.
By the end of this guide, you’ll know whether CPM S35VN is the right steel for your next knife.
What Is CPM S35VN Steel?
CPM S35VN is a premium stainless powder metallurgy steel manufactured in the United States.
It was introduced in 2009 as an improved version of CPM S30V, one of the most successful knife steels ever developed.
Crucible collaborated with renowned knife maker Chris Reeve to create a steel that would offer:
- Better toughness
- Easier machining
- Improved sharpening
- Similar edge retention
- Excellent corrosion resistance
The result was CPM S35VN.
The “CPM” designation stands for Crucible Particle Metallurgy, a manufacturing process that produces an extremely fine and uniform carbide structure.
This advanced manufacturing method helps S35VN achieve a combination of properties that would be difficult to obtain using traditional steel production methods.
Today, S35VN remains one of the most widely used premium knife steels in the industry.
CPM S35VN Chemical Composition
The typical composition of CPM S35VN is:
| Element | Percentage |
|---|---|
| Carbon | 1.38% |
| Chromium | 14.0% |
| Vanadium | 3.0% |
| Niobium | 0.5% |
| Molybdenum | 2.0% |
Each element contributes unique characteristics.
Carbon (1.38%)
Carbon increases hardness, strength, and edge retention.
Chromium (14%)
Chromium provides corrosion resistance and helps form wear-resistant carbides.
Vanadium (3%)
Vanadium contributes to edge retention through the formation of hard vanadium carbides.
Niobium (0.5%)
The addition of niobium was one of the major improvements over S30V.
Niobium helps:
- Increase toughness
- Refine carbide structure
- Improve machinability
Molybdenum (2%)
Molybdenum improves corrosion resistance, strength, and hardenability.
Together, these elements create one of the most balanced stainless knife steels available.
The CPM Manufacturing Process
One reason S35VN performs so well is its powder metallurgy manufacturing process.
Traditional steel production often creates:
- Large carbide clusters
- Uneven microstructures
- Reduced toughness
CPM production solves these issues.
The process involves:
- Melting the alloy.
- Atomizing it into microscopic powder particles.
- Compressing the powder.
- Consolidating it into steel billets.
The result is:
- Uniform carbide distribution
- Improved toughness
- Better edge stability
- Consistent performance
This manufacturing process is one reason S35VN remains highly regarded among knife makers.
CPM S35VN Hardness
Most manufacturers heat treat S35VN between:
58–61 HRC
Premium manufacturers commonly target:
59–60 HRC
Custom makers may occasionally push it slightly higher.
At this hardness range, S35VN achieves an excellent balance between:
- Edge retention
- Toughness
- Corrosion resistance
- Ease of sharpening
Proper heat treatment has a major impact on performance.
A well-heat-treated S35VN blade will often outperform a poorly heat-treated blade made from a theoretically superior steel.
Edge Retention
Edge retention refers to how long a knife stays sharp during use.
S35VN offers excellent edge retention.
Compared to conventional stainless steels such as:
- 440C
- AUS-8
- VG10
- N690
S35VN generally holds an edge significantly longer.
However, it is not an extreme wear-resistant steel.
Compared to:
- M390
- CPM 20CV
- S90V
- S110V
S35VN loses some ground in pure edge retention.
This tradeoff is intentional.
Instead of maximizing wear resistance at all costs, S35VN focuses on providing a practical balance of properties.
For most users, edge retention is more than sufficient for daily tasks.
Toughness
One of S35VN’s greatest strengths is toughness.
Compared to many premium stainless steels, S35VN offers impressive resistance to chipping and edge damage.
The addition of niobium improves toughness compared to S30V.
This makes S35VN suitable for:
- Everyday carry knives
- Outdoor knives
- Hunting knives
- Tactical knives
- Work knives
Although it is not as tough as MagnaCut, CPM 3V, or CruWear, it performs very well among stainless steels.
For real-world users, this toughness often matters more than maximizing edge retention.
Corrosion Resistance
S35VN is a true stainless steel.
Its chromium content provides excellent resistance to:
- Rust
- Staining
- Humidity
- Sweat
- Food acids
This makes it an excellent choice for:
- EDC knives
- Kitchen knives
- Fishing knives
- Coastal environments
- High-humidity climates
Most users find S35VN extremely easy to maintain.
Unlike tool steels such as D2, K390, or 52100, it requires minimal corrosion protection.
Wear Resistance
Wear resistance refers to a steel’s ability to resist abrasive wear during cutting.
S35VN performs very well in this category.
The combination of vanadium carbides and powder metallurgy manufacturing allows the edge to resist abrasion from:
- Cardboard
- Rope
- Leather
- Packaging materials
- Fibrous materials
Although it doesn’t reach the wear resistance levels of S90V or M390, it remains more than capable for most practical cutting applications.
Sharpening CPM S35VN
Sharpening is an area where S35VN shines.
Many premium steels offer exceptional edge retention but can be frustrating to sharpen.
S35VN strikes a better balance.
Compared to:
- S90V
- S110V
- Maxamet
- M390
S35VN is noticeably easier to sharpen.
Most users can achieve excellent results using:
- Diamond stones
- Ceramic stones
- High-quality water stones
The steel also responds well to stropping.
This allows users to maintain a sharp edge for extended periods between full sharpening sessions.
S35VN for Everyday Carry (EDC)
S35VN became especially popular in the EDC community because it offers a near-ideal balance of characteristics.
EDC users typically want:
- Good edge retention
- Corrosion resistance
- Toughness
- Easy maintenance
S35VN delivers all four.
Common EDC tasks include:
- Opening packages
- Cutting cardboard
- Food preparation
- Utility cutting
- General daily use
For these applications, S35VN remains one of the most practical premium steels available.
S35VN for Outdoor and Hunting Knives
Outdoor users appreciate S35VN because it combines stainless performance with respectable toughness.
Advantages include:
- Resistance to weather
- Long edge life
- Easy maintenance
- Reliable field performance
Hunters benefit from its ability to process game while resisting corrosion from moisture and organic materials.
Campers appreciate its versatility for food preparation, rope cutting, and general campsite tasks.
This combination of toughness and corrosion resistance makes S35VN an excellent outdoor steel.
