Selecting the proper knife steel is a matter of prioritizing performance, durability, and purpose. The knife community often debates two popular choices—Nitro-V and S35VN—amongst enthusiasts and professionals. Which one maintains an edge longer? Which one is superior in toughness when subjected to stress? This article explores the minutiae of the two luxury steels, analyzing their pros and cons for the purpose of making a clear choice for you. No matter if you are a collector, a person who loves outdoor activities, or a professional requiring trustworthy tools, this comparison will walk you through the essential considerations when choosing between Nitro-V and S35VN.
Introduction to Knife Steel Selection
The Choice of Material in Knife Production is Essential
The material choice, being one of the most critical ones, is the main factor that determines a knife’s performance, durability, and usefulness. The latest knife steels Nitro-V and S35VN are the product of metallurgical processes, representing the future in the field, and covering the current demands for metals – from good resistance to corrosion to great retention of the edge. Getting the right steel can totally turn a knife’s performance in terms of keeping its sharpness, being able to take heavy usage, and standing tough against bad weather.
One of the instances can be cited is Nitro-V, the nitrogen-infused stainless steel that has the best rust-resistance and toughness properties. The mixture has vanadium and nitrogen in it which gives it high wear-resistance but at the same time does not work against the sharpening process. The knives made with Nitro-V can be used in places where humidity and water exposure are high, so they will serve well in outdoor and marine activities.
Edge Retention and Toughness: an Overview
Edge Retention
Edge retention, which is a significant aspect of knife characteristics, is influenced by the blade’s hardness (measured in Rockwell Hardness Scale, HRC), the type of steel alloy used, and heat treatment. HRC=58-60 or even more for example. The edge retention property of the high-carbon steels like CPM-S90V and ZDP-189 is due to their high carbide volume, which is a plus but during sharpening the process can become tedious. A recent research has shown that CPM-S90V has been able to keep pace with major steel competitors in edge retention ability. Under controlled cutting scenarios, it was able to retain an edge tolerance of approx. 50% longer than the most standard steels.
Toughness
Toughness, in contrast, is important for the blades that are subjected to high lateral forces and impacts. Developed for this situation, steels like CPM-3V and AEB-L are the ones that take the hardest blows without showing break or chip signs. The strength and toughness of these steels have been empirically established, e.g., the testing records show that CPM-3V can bear the lateral stress of 10 times that of harder and more brittle steels like VG-10. This is the reason why it is used in making camping or survival knives, etc.
Finding the Right Mix
Manufacturers frequently cooperate closely with the target market in tailoring steel compositions and blade designs. In that connection, the outdoor plasticity in steel may be about 5160, while the cooking art would demand the sharpness of VG-10 or SG2. Also, the industry has been propped up by the discovery of new methods such as powder metallurgy or differential heat treatment, creating steel that would more likely possess equal shares of edge retention and toughness.
Nitro-V Steel: Composition and Properties
The Details of Nitro-V Steel Chemical Composition
Nitro-V is a pure steel which has undergone the martensitic process, and therefore, it has the ability of rough and tough just at the perfect point of corrosion resistance, durability, and edge retention. It is an improvement of the well-known AEB-L steel, Nitro-V, which has the addition of nitrogen and vanadium that results in better properties. Below is its standard chemical make-up:
| Element | Percentage | Function |
|---|---|---|
| Carbon (C) | 0.68% – 0.72% | Main factor in hardness and edge retention; guarantees fine grain structure and properties of strength and toughness |
| Chromium (Cr) | 12.0% – 13.0% | Major role in resistance to corrosion and keeping steel sharp longer; classifies as stainless steel |
| Vanadium (V) | 0.10% – 0.15% | Raises resistance to wear; creates vanadium carbides for higher edge stability and toughness |
| Nitrogen (N) | 0.08% – 0.11% | Strengthens steel matrix; provides resistance to pitting; enhances durability in extreme conditions |
| Manganese (Mn) | 0.35% – 0.45% | Works with heat treatment by making steel hard; increases overall strength |
| Silicon (Si) | 0.35% – 0.45% | Essential for strength increase; assists during deoxidation process in steel production |
| Phosphorus (P) and Sulfur (S) | ≤ 0.03% each | Limited to very low levels to prevent influence on toughness and brittleness resistance |
S35VN Steel: Composition and Properties
Chemical Composition of S35VN Steel
S35VN steel is an excellent stainless steel characterized by a good combination of toughness, edge retention, and corrosion resistance. It was created by the Crucible Industries as a successor to the already famous S30V steel, adding niobium for better properties. The chemical components of S35VN steel are listed below:

The S35VN steel is a jack-of-all-trades with a harmonious performance throughout major categories, thus it is a premium choice for both industrial and knife-making applications, however, the characteristics of S35VN come out as below in detail:
- Edge Retention: Vanadium carbides having a high percentage of around (3%) make S35VN superb when it comes to edge retention which is the reason why it is preferred for cutting tools that need to be sharp for a long time.
- Corrosion Resistance: With a considerable amount of chromium that is around 14%, S35VN gets a powerful shield against corrosion and rust attack even when the environment is very harsh. This property is particularly an advantage for the outdoor knives that are constantly in contact with moisture and humidity as it becomes a non-issue for the knife users.
- Toughness: The alloying of niobium with the main components of the steel does modify the toughness to a great extent by introducing a factor that reduces the occurrence of chipping or cracking even under heavy use. Thus, S35VN steel’s performance in tough conditions is better compared to steels like S30V.
- Wear Resistance: The presence of an equal proportion of carbon, vanadium as well as niobium carbides secures a very high level of wear resistance. S35VN steel offers continuous slicing for a long time before the need for sharpening arises thereby resulting in less interrupted usage.
- Hardness: Depending on the heat treatment S35VN steel gets a Rockwell Hardness (HRC) of about 58-61. The mentioned hardness is conferring a cutting-edge balance between the durability of the steel and the easiness of sharpening.
Comparative Analysis: Nitro-V vs S35VN
