CPM-3V and CPM-S35VN are two high-quality steels that are known for their toughness, edge retention, and overall top-tier performance. However, they do differ in some ways which are worth mentioning. So in this article, we will compare these two steel to see which is better and why.
Short Answer:
CPM-3V is a tougher steel with better edge retention but is not stainless. CPM-S35VN is a stainless steel but will not be as tough as 3V.
Now that we have looked at the short answer, we can look at each steel individually, how these steels compare in-depth, and the best knives in each steel.
In-Depth Look at CPM-3V
CPM-3V is a tool steel known for its extreme toughness and ability to withstand heavy-duty use. However, where it is lacking is in corrosion resistance and is therefore not an ideal steels for wet or humid environments.
This steel has a high carbon content of 1.3%, a low chromium content of 7.5%, and a tungsten content of 2.75%.
Toughness: The standout feature of CPM-3V is its exceptional toughness, its composition makes it resistant to chipping and breakage even under extreme use.
Edge Retention: The edge retention of CPM-3V is exceptional. It has edge retention similar to other high-end steels like M390. However, it does not have the edge retention of some specialty steels like S110V or S90V.
Corrosion Resistance: It has moderate corrosion resistance, but it will require maintenance to prevent rust. This is because of its low chromium content which is the main component of corrosion resistance.
In-Depth Look at CPM-S35VN
CPM-S35VN is a stainless steel known for its excellent balance of edge retention, corrosion resistance, and ease of sharpening. You can think of this steel as being extremely well rounded in all aspects.
Composition: CPM-S35VN consists of 1.40% carbon, 14% chromium, 3% vanadium, and 2% molybdenum, offering a well-rounded composition.
Edge Retention: CPM-S35VN has good edge retention that is sure to not disappoint any knife user. S35VN has a good balance of ease of sharpening and edge retention and the ability to get a fine and extremely sharp blade.
Corrosion Resistance: Because of the higher chromium content this steel has, it will have no issue keeping off rust and other stains.
Toughness: Regarding toughness, S35VN will hold its own under intense use. Its high carbon content and balance with other elements such as vanadium and molybdenum make it an excellent steel to hold up to chopping tasks.
In-Depth Comparison
Toughness: CPM-3V is renowned for its exceptional toughness, making it suitable for applications where the blade undergoes high stress like chopping. In contrast, CPM-S35VN, while tough, might not withstand extreme impacts as well.
Edge Retention: CPM-3V is the better steel for edge retention because it is a tougher steel and therefore will hold an edge better.
Corrosion Resistance: CPM-S35VN has superior corrosion resistance due to its higher chromium content, making it more suitable for environments with high humidity or exposure to water.
Sharpening: CPM-S35VN is easier to sharpen compared to CPM-3V. So it will take less time to get back to sharp and will be better at getting a finer edge.
