In the world of high-performance Tools, the steel used in a blade is often the deciding factor between a good knife and a legendary one. For collectors and daily users seeking the pinnacle of edge retention and corrosion resistance without spending thousands, M390 steel is the gold standard.
Often referred to as a "super steel," M390 has revolutionized the EDC (Everyday Carry) market by offering professional-grade performance in accessible folding designs. In this guide, we dive into what makes this steel special and recommend five of the most popular M390 knives released in the last few years that provide incredible value.
What is M390 Steel?
Böhler M390 Microclean is a third-generation powder metallurgy stainless steel produced by Böhler-Uddeholm. It is specifically engineered to provide a unique combination of high wear resistance and extreme corrosion resistance.
The secret lies in its chemical composition, which features a high concentration of chromium and vanadium. Because it is a powder metallurgy steel, the carbides are distributed very finely and evenly. This allow manufacturers to grind the blade to a razor-sharp edge that lasts significantly longer than traditional budget steels. For Tools that face daily use, M390 offers a "set it and forget it" level of performance, staying sharp through countless cutting tasks.
M390 vs. Other Premium Steels
When building your EDC kit, you might encounter other high-end materials. Here is how M390 stacks up:
-
M390 vs. S35VN: While S35VN is a fantastic all-around steel, M390 generally offers superior edge retention. S35VN is slightly tougher and easier to sharpen, but M390 is the clear winner for those who want their edge to last as long as possible.
-
M390 vs. D2: D2 is a popular "tool steel," but it lacks the corrosion resistance of M390. M390 is a true stainless steel, meaning it won't rust as easily when exposed to moisture or acidic materials.
-
M390 vs. CPM 20CV: These steels are virtually identical in performance. If you love M390, you will find 20CV to be just as capable, as they share nearly the same chemical blueprint.
