CPM S110V Steel Review
If edge retention is your highest priority when choosing a knife, CPM S110V deserves serious attention. CPM S110V is widely regarded as one of the most advanced stainless powder metallurgy steels available for premium knives. Its unique combination of high vanadium and niobium carbides delivers extraordinary wear resistance, allowing knives made from this steel to stay sharp through prolonged cutting tasks that would quickly dull many other premium steels.
However, exceptional edge retention comes with trade-offs. CPM S110V is more challenging to sharpen than most knife steels, and its toughness is lower than newer balanced steels like MagnaCut. For some users, these compromises are well worth it. For others, they may be a reason to choose a different steel.
So, is CPM S110V worth the premium price? How does it compare with CPM S90V, M390, MagnaCut, or Elmax? And is it suitable for everyday carry or outdoor use?
In this comprehensive review, we’ll examine every important aspect of CPM S110V, including its composition, manufacturing process, real-world performance, sharpening characteristics, corrosion resistance, and comparisons with other premium knife steels.
What Is CPM S110V Steel?
CPM S110V is a high-performance stainless powder metallurgy steel. It was designed to maximize wear resistance while maintaining excellent corrosion resistance and adequate toughness for premium knives.
Unlike conventional stainless steels, CPM S110V contains extremely high amounts of vanadium and niobium. These elements form exceptionally hard carbides that dramatically slow edge wear during cutting.
Originally developed for industrial tooling where long service life was essential, S110V eventually became popular among custom knife makers and premium production manufacturers. Today it is commonly used in high-end folding knives, everyday carry (EDC) knives, hunting knives, and outdoor blades where long-lasting sharpness is a priority.
Because of its advanced alloy design and powder metallurgy manufacturing process, CPM S110V is considered one of the most wear-resistant stainless knife steels commercially available.
What Does CPM Mean?
The “CPM” in CPM S110V stands for Crucible Particle Metallurgy, a manufacturing process that differs significantly from traditional steel production.
Instead of casting molten steel into large ingots, the liquid steel is atomized into microscopic powder particles. These particles rapidly cool, producing a very fine internal structure. The powder is then compressed under extremely high pressure and temperature to create solid steel billets.
This manufacturing method offers several important advantages:
- Extremely fine grain structure
- Uniform carbide distribution
- Better edge stability
- Improved wear resistance
- Greater manufacturing consistency
- Reduced segregation of alloying elements
Without powder metallurgy, a steel containing as much vanadium and niobium as S110V would be extremely difficult to manufacture successfully.
CPM S110V Chemical Composition
Typical chemical composition is approximately:
| Element | Approximate Content |
|---|---|
| Carbon | 2.80% |
| Chromium | 15.25% |
| Vanadium | 9.00% |
| Niobium | 3.00% |
| Cobalt | 2.50% |
| Molybdenum | 2.25% |
This complex alloy is responsible for S110V’s outstanding performance.
Let’s examine the contribution of each major element.
Carbon
At approximately 2.8% carbon, CPM S110V contains significantly more carbon than most stainless knife steels.
Carbon contributes to:
- High hardness
- Superior wear resistance
- Excellent edge retention
- Carbide formation
This high carbon content allows the steel to support an extremely durable cutting edge.
Chromium
Chromium provides corrosion resistance and also contributes to carbide formation.
With over 15% chromium, CPM S110V qualifies as a true stainless steel and performs exceptionally well in humid environments and during food preparation.
The chromium content also helps reduce staining while maintaining an attractive blade finish.
Vanadium
Vanadium is one of the defining alloying elements in CPM S110V.
At approximately 9% vanadium, the steel develops an enormous volume of extremely hard vanadium carbides.
These carbides greatly improve:
- Edge retention
- Abrasion resistance
- Edge stability
- Fine grain structure
Few commercially available knife steels contain this much vanadium.
Niobium
One of the unique characteristics of CPM S110V is its addition of approximately 3% niobium.
Niobium carbides are even harder than many chromium carbides and contribute additional wear resistance while helping refine the steel’s microstructure.
The addition of niobium is one of the reasons S110V can outperform many other premium steels in edge retention.
Molybdenum
Molybdenum contributes:
- Corrosion resistance
- Hardenability
- Strength
- High-temperature stability
It also supports the steel’s balanced heat treatment characteristics.
Cobalt
Cobalt improves heat treatment response and helps the steel achieve high hardness while maintaining structural stability.
CPM S110V Hardness
Most manufacturers heat treat CPM S110V between 60 and 62 HRC.
Some custom makers may target slightly higher hardness levels, but increasing hardness generally reduces toughness.
At approximately 61 HRC, S110V provides an excellent balance between edge stability and cutting performance.

Edge Retention
Edge retention is where CPM S110V truly distinguishes itself.
Thanks to its exceptionally high volume of vanadium and niobium carbides, S110V can continue cutting effectively long after many other premium knife steels require sharpening.
Independent cutting tests consistently place CPM S110V among the very best stainless steels for long-term edge retention.
Users who cut abrasive materials such as cardboard, rope, leather, or heavy packaging often notice dramatic improvements in cutting longevity compared with steels like VG10, 154CM, or even M390.
For people who dislike frequent sharpening, CPM S110V is one of the strongest choices available.
Wear Resistance
Wear resistance refers to the steel’s ability to resist gradual material loss as the edge cuts abrasive materials.
Few stainless knife steels outperform CPM S110V in this category.
Its exceptional carbide volume allows the edge to resist abrasion during prolonged cutting tasks.
This makes S110V particularly well suited for:
- Cardboard
- Rope
- Carpet
- Leather
- Plastic packaging
- Synthetic fabrics
- Heavy utility work
Users who process large amounts of abrasive material often appreciate how little edge degradation occurs.

- Cutting frozen materials
- Heavy survival tasks
Instead, it excels in controlled cutting applications where edge retention is more important than impact resistance.
Is CPM S110V Difficult to Sharpen?
One of the most common criticisms of CPM S110V is that it takes longer to sharpen than most knife steels.
This reputation is largely accurate.
The steel’s high concentration of vanadium and niobium carbides makes it highly resistant to abrasion, meaning sharpening stones remove material more slowly.
Diamond stones or high-quality ceramic abrasives generally provide the best results.
Fortunately, S110V requires sharpening much less frequently than most steels, partially offsetting the additional sharpening time.

The History of CPM S110V
Crucible Industries has long been recognized as a pioneer in powder metallurgy technology. After the success of earlier CPM steels such as S30V and S90V, the company sought to create a stainless steel with even greater wear resistance while preserving the corrosion resistance demanded by modern knife users.
The result was CPM S110V.
By increasing both vanadium and niobium content, Crucible developed a steel capable of supporting one of the highest carbide volumes found in commercial knife steels. These carbides dramatically improved abrasion resistance, allowing knives to maintain a sharp edge through exceptionally long cutting sessions.
Although S110V was originally developed for industrial tooling, premium knife manufacturers quickly recognized its potential. Today, it is commonly found in high-end production knives and custom builds aimed at enthusiasts who value maximum edge retention.
Despite the arrival of newer steels such as MagnaCut and Vanax, CPM S110V remains one of the benchmarks for wear-resistant stainless knife steels.
