Bohler M390 Knives: Austrian-Made Super Steel with World-Class Edge Retention & Corrosion Resistance

Bohler M390 is one of the most respected and widely used premium knife steels in the world, and for good reason. Produced by Bohler-Uddeholm in Austria using a proprietary powder metallurgy process, M390 is a third-generation stainless steel that delivers a combination of edge retention, corrosion resistance, and polishability that has made it a favorite of custom knife makers and premium production brands alike for over a decade. Metallurgically, M390 is virtually identical to CPM 20CV and Carpenter CTS-204P — the three steels share essentially the same alloy composition and deliver comparable real-world performance, making M390 knives a direct equivalent to the finest American-made super steels in terms of cutting ability and rust resistance.

The high vanadium and chromium content in Bohler M390 produces a blade that holds a razor-sharp working edge through demanding cutting tasks and resists corrosion in wet, humid, and even coastal environments better than most production stainless steels. It takes an exceptional mirror polish, which is why it is particularly popular among both premium everyday carry brands and custom makers who want a steel that looks as good as it performs. The honest tradeoff is sharpenability — M390 is not the easiest steel to reprofile from scratch and benefits from diamond or ceramic sharpening tools, though routine edge maintenance on a strop or fine hone is straightforward once the edge geometry is established. Brands like BokerWe KnifeCIVIVI, and Benchmade regularly deploy M390 across their premium production lineups, and knives featuring this steel consistently rank among the most sought-after models in the knife community.
