Evaluating the write-upWthe write-up Resistance of Each Steel
Repairing a knife’s edge is its wear resistance, and it becomes most apparent in heavy or abrasive use scenarios. While both Nitro V and S35VN have considerable wear resistance, they perform differently because of their chemical composition and microstructure. The below write-up compares the wear resistance of both steels in detail:
- Carbide Composition
S35VN: Holds greater share of vanadium carbides which improves wear resistance due to extreme hardness.
Nitro V offers better corrosion resistance but relies more on chromium carbides, which are not as hard as vanadium carbides and, therefore, do not enhance wear resistance as much.
- Shaving Level Steel (Rockwell Hardness – HRC)
S35VN: Widely accepted that it is hardened to a range of 58-61 HRC, offering exceptional tenacity and wear resistance.
Nitro V: It is hardened in a parallel range of 57-60 HRC, which offers decent wear resistance but high ductility.
- Abrasive Use Cases
S35VN: Cutting fibrous or hard materials is a breeze, and maintaining the blade’s edge integrity is extremely easy.
Nitro V performs well whenever a lighter-duty task is required or wear resistance is prioritized over corrosion resistance.
- Edge Stability
S35VN: The greater the share of vanadium carbide content, the better the edge stability during use. This means the edge is slowly degraded over time.
Nitro V: It exhibits slightly softer carbides, inferior edge stability, and enhanced toughness, which prevents chipping under impact.
- Versatility End Use
S35VN: Prefers and performs best with high tacticals and hunting EDC (Every Day Carry) knives designed for extended periods of heavy usage and abrasion taking blades.
Nitro V: Works best with kitchen and fishing knives, where moderate resistance to wear and saltwater combined with superb protection against rust is more important.
These differences show that responsiveness to changes in S35VN is greatly boosted by wear resistance due to vanadium carbides. Nitro V is lacking in this feature but preferred in applications that withstand harsh conditions.
Impact of Edge Geometry on Performance
The performance of a blade, including its cutting efficiency, durability, and functionality all depends on how the blade edge is shaped. The edge angle, thickness, and the type of grind done affect how the blade interacts with materials and its durability over time.
Thin-edge geometry blades, including high-performance flat and hollow grinds, excel in tasks that require slicing due to their exceptional sharpness and precision. Kitchen knives, for example, feature a 15-degree edge angle, which allows for exceptionally clean cuts. The downside, however, comes in the form of durability, as thinner edges are more likely to chip or bend under considerable pressure.
Blades made for outdoor activities, like hunting or survival knives, utilize thicker edge geometry, like saber and convex grinds. These thicker edges make the blades tougher and more stable. Such knives typically have edge angles of around 20 to 25 degrees. This allows the blade to withstand damage during heavy-duty tasks like batoning wood or cutting through dense materials.
A study conducted by blade professionals shows that even slight differences in edge angles can greatly influence performance. One study with like blades (soft materials) showed that changing the edge angle from 20 degrees to 15 degrees increased cutting efficacy by 30%. However, it also reduced edge retention on hard materials by almost 15%.
Another critical consideration is the type of material to be cut. Delicate tasks like food prep are better performed with thinner edges, while tougher geometries are best suited for framing materials like rope, leather, or wood. By contouring the blade’s purpose to its edge geometry, users will increase and maximize efficiency while also ensuring the blade’s longevity.
In the end, the edge geometry is dictated by the application in question for those using high-performance steels like S35VN or Nitro V. Choosing a specific edge design in conjunction with these materials guarantees that the blade yields optimal results regardless of whether the design demands high precision, impact durability, or adaptability.
Which Steel Offers Better Toughness and Corrosion Resistance?
Nitro V usually dominates S35VN in terms of toughness and resistance to corrosion. Nitro V has added nitrogen in its composition, improving its rust resistance, so it is great for very wet or humid areas. Moreover, Nitro V has better toughness, meaning it is less likely to chip or break when impacted and can withstand harsh conditions. S35VN is known for its balanced strength and resistance to wear, but if the most critical factors are toughness and how corroded the steel gets over time, Nitro V is the best choice.

| S35VN | 1950-2050 | 400-600 | 59-62 |
Both Nitro V and S35VN steel benefit tremendously from heat treatment, allowing manufacturers to customize their products as needed. The latest developments in heat treatment techniques, such as cryogenic quenching and vacuum heating, significantly boosted the performance of these steels, allowing even more stringent requirements for consistency and durability in use. These improvements guarantee the steel’s reliability and endurance for the demanding requirements of the aerospace, cutlery, and high-performance tooling industries.
Influence of Heat Treat on Edge Stability of Steel’s edge stability, particularly in high-impact wear-resistant
Heat treatment is critical for steel’s edge stability, particularly in high-impact wear-resistant applications. Below are five elements that heat treatment impacts, with details provided.
- Elevating Microstructure
Heat treatments such as annealing and quenching improve the grain shape within the steel microstructure. Finer grains, which reduce brittleness, aid improved edge retention.
Example Data: Research indicates steels with grain sizes less than 10 microns exhibit a 20% increase in edge stability.
- Hardness Control
The material’s resistance to deformation and ability to maintain sharp edges is retained through regulated heating/cooling cycles for material sharpness resistance.
Example Data: Edge stability of tempered steels with a Rockwell Hardness of 60-62 HRC greatly surpasses that of those with more than 63 HRC due to brittleness compromising performance.
- Carbide Dispersal
Effective heat treatment guarantees proper dispersal of carbides within the steel ensuring high edge durability.
Example Data: Steels with properly dispersed carbides have up to 30% less edge wear during intensive cutting due to the controlled dispersion of carbides.
- Stress Relief
Processes like tempering and cryogenic treatments provide high edge support from loads, lessening internal stresses that may lead to chipping or cracking.
Example Data: After quenching, tempering improves the edge’s stabilization by 15%. At this stage, residual stress is reduced to virtually zero.
- Corrosion Resistance Enhancement
With the proper form of heat treatment for stainless steels, passive oxide layers are formed more uniformly, making them more resistant to edge degradation due to humidity or chemical attacks.
Example Data: Stainless steels that have undergone heat treatment have an increase in resistance to corrosion of about 25% which significantly impacts the longevity of the edge in wet environments.
All of these factors point to the impact of optimum thermal treatment on the design of tools and parts that are intended to have elements with sustained high-performance edges over prolonged durations of time.
