Microtech Amphibian Mini RAM-LOK S/E Black Frag Aluminum, Apocalyptic Böhler M390MK by Tony Marfione – a compact folding knife with a two-handed lock

Microtech Amphibian Mini RAM-LOK S/E Black Frag Aluminum, Apocalyptic Böhler M390MK by Tony Marfione (137MRL-10APFR) is a premium-class compact folding knife that combines an S/E Clip Point blade, Böhler M390MK steel, and aluminum grips with a milled “Frag” texture. The model retains the recognizable Amphibian silhouette while offering smaller dimensions, two-handed operation, and a striking Apocalyptic finish.

The blade can be opened using a dual thumb stud on both sides, and ball bearings ensure smooth operation of the mechanism. The RAM-LOK™ lock is accessible from both sides of the handle, while the reversible tip-up clip allows you to adjust the carry style for either right- or left-handed use.

Böhler M390MK – Microtech’s powder steel for demanding EDC

The blade is made of Böhler M390MK steel with a hardness of 61–62 HRC. This material offers high wear resistance, good corrosion resistance, and long-lasting sharpness. It performs well when cutting cardboard, cords, tape, plastics, and other everyday materials.

S/E Clip Point, Flat, and Apocalyptic

The S/E Clip Point profile provides a precise tip and a versatile cutting edge. The Flat grind helps the blade glide smoothly through the material, while the Apocalyptic finish gives the blade a rugged, weathered look and helps mask minor signs of regular use.

Black Frag Aluminum and RAM-LOK™

The grips are made of 6061-T6 aluminum, and the Frag pattern is milled directly into their surface. It is not an applied texture or a separate layer. The milled geometry improves grip and supports a stable hand position, while the RAM-LOK™ locking mechanism allows for comfortable use 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. Diamond stones, CBN systems, or precision guiding systems work best for sharpening.

How does the RAM-LOK™ lock work?

RAM-LOK™ uses a crossbar that moves within the Handle’s guides. When opened, it locks the blade in place, and access from both sides makes it easy to use with either your right or left hand.

What makes the Frag milled pattern unique?

The Frag pattern is milled directly into the surface of the aluminum grips. It increases the grip of the handle and gives it its distinctive, technical geometry.

What is the dual thumb stud used for?

The double-sided thumb stud allows you to open the blade with the thumb of either your right or left hand. Combined with the two-handed lock and the reversible clip, it increases the knife’s versatility.

What does a tip-up clip mean?

The tip-up configuration means that when the knife is closed, the tip of the blade points upward. The clip can be mounted on the right or left side of the Handle.
