Böhler M390MK – Powder Steel with High Edge Retention

The blade is made of Böhler M390MK steel with a hardness of 61–62 HRC. The material is characterized by high abrasion resistance, good corrosion resistance, and long-lasting sharpness, making it suitable for regular EDC use.

S/E Clip Point, Flat, and Black

The S/E Clip Point profile provides a functional tip and a versatile blade line. The Flat grind supports efficient cutting, while the black blade finish emphasizes the model’s tactical character and creates a cohesive whole with the Black Frag Handle.

Milled Black Frag and Ambidextrous Mechanics

The 6061-T6 aluminum grips feature a Frag pattern milled directly into the surface of the material. This texture improves grip and enhances control of the knife during use. The RAM-LOK™ lock, dual thumb studs, and reversible clip allow for comfortable operation with either the right or left hand.

Technical data

Frequently Asked Questions

How do I care for and sharpen Böhler M390MK steel?

After use, clean the blade and dry it thoroughly. For sharpening, we recommend using diamond stones, CBN systems, or precision guide systems.

How does RAM-LOK™ work?

RAM-LOK™ uses a crossbar that locks the blade in place when opened. The mechanism is accessible from both sides of the Handle, so it can be conveniently operated with either the right or left hand.

Is the Frag pattern applied to the surface?

No. The Frag pattern is milled directly into the surface of the aluminum grips. It is an integral part of the Handle and improves its grip.

What are the advantages of the Amphibian Mini’s design?

The Amphibian Mini retains the functional geometry of the full-size series in a more compact format. Its shorter length makes it easier to carry daily, while maintaining a comfortable handle and the full functionality of a folding knife.

What does “tip-up clip” mean?

“Tip-up” means that when the knife is closed, the tip of the blade points upward. The clip can be moved to the right or left side of the Handle.
