What is M390 Steel?
The Böhler M390 is a premium martensitic stainless steel developed using microclean powder metallurgy technology. Renowned for its exceptional edge retention, corrosion resistance, and toughness, M390 is a favorite among custom knife makers and high-end manufacturers.
Why M390 is Superior
-
Exceptional Edge Retention: M390 stays sharp longer than many other steels, making it ideal for repeated use.
-
High Corrosion Resistance: The chromium content (20%) ensures protection against rust and staining even in harsh environments.
-
Superior Toughness: The fine carbide structure provides a perfect balance between hardness (60-62 HRC) and durability.
Vacuum Deep-Cold Heat Treatment
To maximize the steel’s potential, the 'Eagle' undergoes vacuum heat treatment followed by deep cryogenic processing. This enhances:
-
Blade hardness for long-lasting sharpness.
-
Structural integrity to prevent micro-fractures.
-
Wear resistance for extended lifespan.
The result is a blade that performs exceptionally in cutting, slicing, and piercing tasks, whether for outdoor adventures or daily utility.
2. Exquisite Craftsmanship: Hand-Forged & Engraved
Hand-Forged Construction
Unlike mass-produced knives, the Eagle series is hand-forged to ensure superior quality control and attention to detail. Each blade is individually shaped, heat-treated and finished by skilled craftsmen.
Tang Grass Engraving
The blade features an elegant "Tang grass" engraving near the tip—A traditional motif that symbolizes toughness and natural beauty. This artistry enhances the knife's beauty while paying homage to classic knifemaking traditions.
Rosewood Handle: Beauty & Ergonomics
The handle is crafted from high-quality rosewood, known for its:
-
Rich, natural grain patterns that make each knife unique.
-
Smooth, polished finish for a luxurious grip.
-
Durability and resistance to moisture for long-term use.
After multiple polishing stages, the handle achieves a silky-smooth texture, ensuring comfort even during prolonged use.
3. Precision Engineering: Smooth Deployment & Reliability
Ceramic Ball Bearing Pivot System
The 'Eagle' features a high-precision ceramic ball bearing pivot, ensuring:
-
Buttery-smooth opening and closing with minimal friction.

Secure Locking Mechanism
A robust liner lock or frame lock (depending on the variant) keeps the blade securely in place during use, preventing accidental closures.
