1. What is M390 Steel?
M390 steel is a premium-grade stainless steel developed by Böhler Edelstahl GmbH, a leading producer of high-performance materials. Known for its third-generation powder metallurgy process, Böhler has engineered a type of steel that excels in sharpness retention, corrosion resistance, and wear resistance. This steel contains a carefully balanced mix of vanadium, chromium, and molybdenum, making it one of the most advanced alloy compositions on the market.But what sets M390 steel apart from other knife steels? It’s the fact that it is also great for use in applications where performance is essential. Many knife makers consider it a “super steel” due to its extremely high edge retention and resistance to wear and tear. In short, M390 is built to last.
2. Why Do Knife Enthusiasts Prefer M390?
Superior Wear Resistance
One of the standout features of M390 steel is its excellent wear resistance. The steel is designed to handle wear and tear without compromising its cutting ability. This makes it ideal for EDC knives, fixed blades, and even kitchen knives where frequent use is expected.
Exceptional Edge Retention
M390 knives are renowned for their superior edge retention. This means you won’t need to sharpen your knife as often compared to blades made from other types of steel. Thanks to its high percentage of chromium and vanadium, the blade maintains its sharpness longer, ensuring that your knife will last longer and deliver consistent performance.
3. How Does M390 Achieve its High Corrosion Resistance?
M390 steel is part of the stainless steels category, boasting good corrosion resistance due to its high chromium content. This makes it ideal for environments prone to moisture, humidity, or even saltwater exposure. Whether you’re using it for outdoor camping trips or in a kitchen knife, M390’s corrosion resistance ensures that your blade stays rust-free with minimal maintenance.
4. What Makes M390 a “Super Steel”?
The term “super steel” isn’t just a marketing buzzword—it highlights the exceptional properties that make M390 steel excel in various applications. Here are a few reasons why M390 deserves the title:
- High Carbon Content: This contributes to its high hardness, making it a tough, durable material.
- Powder Metallurgy Process: The unique manufacturing process ensures a uniform distribution of different elements like molybdenum and chromium, enhancing the toughness and wear resistance of the steel.
- Versatility: From EDC knives to fixed blades, M390 knives are perfect for a wide range of uses.
5. How Does Böhler Produce M390 Steel?
The creation of M390 involves advanced technology and precision. Böhler produces this steel using their patented third-generation powder metallurgy. This process ensures a fine-grain structure, which is key to achieving excellent sharpness retention and edge retention and corrosion resistance. The result? A blade that’s not only sharp but also incredibly durable.
6. Is M390 Easy to Sharpen?
While M390 steel is prized for its sharpness retention, some users wonder whether it’s easy to maintain. The answer lies in the balance between its hardness and grindability. Although it’s not as simple to hone as softer steels, using the right tools—such as a sharpening stone or diamond-coated sharpeners—makes the process manageable. A leather strop can also help maintain the shape of the edge, ensuring your blade delivers excellent sharpness every time.
7. How Does M390 Compare to Other Popular Knife Steels?
Comparing M390 steel with other types of steel reveals just how it excels in key areas like corrosion resistance, wear resistance, and edge retention.
| Property | M390 Steel | D2 Steel | 20CV Steel |
| Edge Retention | Superior | Good | Comparable to M390 |
| Corrosion Resistance | Excellent | Moderate | Excellent |
| Ease of Sharpening | Moderate | Easier | Moderate |
| Wear Resistance | Exceptional | High | Exceptional |
As shown in the table, M390 is one of the leading choices for knife manufacturers who want a balance of sharpness, durability, and resistance to the elements.
8. What Knives Benefit Most from M390 Steel?
Due to its versatility, M390 steel is widely used across various knife types. Some examples include:
- Pocket knives: Lightweight yet durable, perfect for everyday carry.
- Fixed blades: Built to handle tough outdoor tasks.
- Kitchen knives: Ensures precision cutting and long-lasting performance.
Whether you’re looking for a sharp knife for your collection or a blade that can handle heavy-duty tasks, knives with M390 are a reliable choice.
9. How Does Heat Treatment Enhance M390 Steel?
The secret to unlocking M390’s full potential lies in its heat treatment. Properly heat treating the steel enhances its hardness, toughness, and wear resistance. Most knife makers subject M390 to a Rockwell hardness of 60-62 HRC, ensuring it’s tough enough to withstand rigorous use while retaining its edge.
10. Why Choose Knives Made from M390 Steel?
If you’re still on the fence about investing in an M390 knife, here are some compelling reasons:
- Performance is Essential: M390 excels in high-performance applications, making it ideal for both professionals and enthusiasts.
- Built to Last: Thanks to its excellent wear resistance and corrosion resistance, an M390 steel blade is a long-term investment.
- Great for Use in Knives: Whether it’s for camping, cooking, or everyday tasks, M390 delivers unmatched reliability and sharpness.
