Böhler M390 is a powder-metallurgical, rust-resistant high-performance steel from Böhler. It combines very high edge retention with high corrosion resistance and is one of the most popular premium knife steels for high-quality EDC, outdoor, and pocket knives.
Three key characteristics of the steel: Edge Retention, Rust Resistance, and Sharpenability
Edge Retention: very high
★★★★★
The high proportion of hard chromium and vanadium carbides ensures excellent wear resistance. This keeps the edge sharp for a long time, even with intensive use.
Rust Resistance: high
★★★★★
With around 20% chromium, M390 offers high corrosion resistance and is well-suited for use in humid environments or for daily use.
Sharpenability: medium
★★★☆☆
The high wear resistance makes sharpening more elaborate than with simply alloyed knife steels. However, a very fine edge can be achieved with high-quality abrasives.
Areas of Application
EDC & Pocket Knives: The combination of high edge retention, corrosion resistance, and good toughness makes M390 one of the most popular premium steels for high-quality everyday knives.
Outdoor Knives: The high wear resistance and corrosion resistance are suitable for versatile uses in changing weather conditions.
Hunting Knives: Good corrosion resistance and long edge life are advantageous for demanding cutting tasks.
Kitchen Knives: M390 is also suitable for high-quality kitchen knives when long edge retention and high corrosion resistance are required.
