When it comes to high-end Tools, the heart of any premium knife is its blade steel. Among the elite "super steels" that dominate the market today, Böhler M390 stands as a titan. Known for its incredible edge retention and corrosion resistance, it has become the gold standard for enthusiasts looking for the perfect EDC (Everyday Carry) companion.
In this guide, we’ll dive into what makes M390 so special, how it stacks up against the competition, and our top five recommendations for folders and fixed blades released in recent years.
What is M390 Steel?
Böhler M390 is a "third-generation" powder metallurgy stainless steel. Developed by Böhler-Uddeholm, it was originally designed for use in industrial molds that require extreme wear resistance and the ability to withstand corrosive plastics.
For the knife world, these properties translate into a blade that stays sharp for an incredibly long time, even after heavy use. Because of its high chromium content, it is also exceptionally resistant to rust, making it a low-maintenance choice for humid environments or food preparation.
M390 vs. The Competition
To understand why M390 is a top-tier choice for your Tools collection, it’s helpful to see how it compares to other popular premium steels:
| Steel Type | Edge Retention | Toughness | Corrosion Resistance | Ease of Sharpening |
| M390 | Exceptional | Moderate | Excellent | Challenging |
| CPM-S35VN | Great | High | Great | Moderate |
| CPM-Magnacut | Great | Very High | Exceptional | Moderate |
| D2 (Budget) | Good | Moderate | Low | Moderate |
While steels like Magnacut offer higher toughness (resistance to chipping), M390 remains a favorite for EDC folders because its edge holding is virtually unmatched in daily slicing tasks. Compared to more affordable options like S35VN, M390 will keep its "razor" edge significantly longer, though it requires diamond stones and a bit more patience when it finally comes time to sharpen.
Top 5 M390 Knife Recommendations
Here are five of the most popular and highly-regarded M390 knives released by leading brands in the last five years.
1. Bestech Seraph
The Bestech Seraph is a masterclass in modern knife manufacturing. Bestech has rapidly ascended the ranks of premium knife makers, and the Seraph showcases why. Featuring a sleek, aerodynamic silhouette, this flipper folder utilizes a high-performance M390 blade paired with a meticulously machined titanium handle. The action is butter-smooth thanks to ceramic ball bearings, making it a joy to deploy. As a sophisticated EDC option, it balances tactical efficiency with a "gentleman’s folder" aesthetic, ensuring it looks just as good in a pocket as it does in action.
2. Benchmade Bugout (M390 Aluminum Edition)
The Bugout is a legend in the knife community, but the recent M390 upgrade elevated it from a lightweight tool to a premium powerhouse. This version replaces the standard Grivory scales with milled aircraft-grade aluminum, providing a more robust feel in the hand without sacrificing the slim profile that made it famous. The M390 blade ensures that this featherweight folder can handle long-term cutting tasks without needing a touch-up. It is widely considered one of the best versatile Tools for hikers, commuters, and collectors alike.
3. Microtech Ultratech
For those who prefer an "Out-The-Front" (OTF) automatic, the Microtech Ultratech remains the industry benchmark. In recent production runs, Microtech has heavily utilized M390 for its flagship models. The Ultratech offers lightning-fast deployment and retraction with a single thumb slide. Because OTF knives are often used for quick, repetitive tasks, the wear resistance of M390 is a perfect match. Its precision engineering and aggressive styling make it a standout piece of gear for anyone who values technical excellence and reliability.
4. LionSteel M7 (Fixed Blade)
While M390 is most common in folders, the LionSteel M7 proves it can thrive in a fixed-blade format. This Italian-made powerhouse features a "Solid" handle—milled from a single piece of Micarta—providing incredible ergonomic comfort and strength. The M7 is designed as a heavy-duty field knife. While M390 is generally optimized for slicing, LionSteel’s expert heat treatment allows this large blade to tackle camping chores and outdoor survival tasks with ease, all while maintaining a stainless finish that resists the elements.
5. Zero Tolerance 0562CF
The ZT 0562CF, designed by Rick Hinderer, is often cited as one of the best production knives ever made. While the model has existed for some time, recent iterations featuring M390 steel have cemented its status as a "grail" knife for many. It features a carbon fiber front scale and a titanium frame lock, providing a perfect blend of weight savings and strength. The "slicer" grind on the M390 blade provides incredible cutting geometry, making it one of the most efficient high-end Tools available for heavy daily use.
Conclusion: Is M390 Right for You?
If you are looking for a knife that represents the pinnacle of modern metallurgy, M390 is a fantastic choice. It offers a "set it and forget it" level of sharpness that is ideal for EDC enthusiasts who don't want to sharpen their blade every week. Whether you choose a precision flipper from Bestech or a rugged fixed blade from LionSteel, an M390 blade is an investment in quality that will last a lifetime.
