Developed by the American company Crucible Industries, CPM-S30V is a martensitic (hardened) powder-made stainless steel, widely used in high-end premium pocket knives. Known for its excellent corrosion resistance and superior edge retention, this high-grade knife steel ranks among the best for EDC knives. In addition, it offers above-average durability and excellent resistance to wear.
Advantages of S30V as Knife Steel
The benefits of using S30V in EDC knives are numerous. Thanks to its superior edge retention, this steel can hold its sharp edge for extended periods, reducing the frequency of sharpening. Besides, it offers a high level of corrosion resistance, making it suitable for use in different environments.
Furthermore, its hardness and excellent wear resistance ensure that your knife remains durable even with constant use. Additionally, being a stainless steel, CPM-S30V is easy to clean and maintain, providing convenience for users.
Disadvantages of S30V for Knives
Despite its many advantages, S30V does have its drawbacks. The most notable is difficulty in sharpening, particularly for beginners due to its hardness. Besides, it has a relatively high cost compared to other steel grades, although this is reflective of its high quality and performance.

Is S30V Rust Resistant?
CPM-S30V features excellent corrosion resistance, standing up well against rust. Thanks to its high chromium content, it is highly resistant to oxidization, making it ideal for use in humid environments where rust is a concern. Proper maintenance and cleaning further enhance its rust resistance.
How Durable is S30V?
S30V possesses a hardness rating of 59-61 HRC, which is considered high among knife steels. This high hardness level accounts for the steel's excellent edge retention and wear resistance properties. With this hardness rating, knives made of CPM-S30V are suitable for demanding cutting tasks while maintaining their edge.
Widely known for its balance of edge retention, corrosion resistance and durability, CPM-S30V is one of the most popular knife steels on the market. It is commonly used in premium quality EDC knives, hunting knives, kitchen knives and other types of high-performance tools.
In conclusion, if you are looking for a high-grade knife steel that offers an ideal balance of all essential properties (edge retention, wear resistance, corrosion resistance, and toughness), CPM-S30V is hard to beat. Despite requiring a bit more effort in sharpening and coming at a higher cost, its overall performance and durability make it worth consideration for any EDC knife.
