The Microtech Amphibian RAM-LOK 137RL-1FLDB-X19Z23 is a full-size folding knife designed by Tony Marfione, combining an M390MK steel blade with a milled aluminum handle in Dark Burnt Bronze. The design features a RAM-LOK lock, ball bearings, and thumb studs on both sides.
The 98.43 mm blade features a Clip Point profile, a hollow grind, and an Apocalyptic Bronze finish. The Cerakote coating gives the surface its distinctive color, while the substantial handle with milled panels ensures a secure grip while maintaining the model’s bold, technical character.
M390MK – Steel Developed for Microtech
The blade is made of M390MK steel, a grade developed for Microtech in collaboration with Böhler. This material maintains high resistance to wear and corrosion, offering performance tailored to the demands of modern premium folding knives.
Clip Point, hollow grind, and Bronze Apocalyptic
The Clip Point profile ensures a distinct tip and good control during precision work. The hollow grind supports efficient cutting, while the Bronze Apocalyptic finish gives the blade an aged, well-worn character. The Cerakote coating gives the surface its brown color and additionally protects the steel from environmental factors.
Dark Burnt Bronze Aluminum and RAM-LOK
The handle is made of aluminum and finished in Dark Burnt Bronze. The milled surface increases grip, and the Burnt Bronze-colored titanium backspacer complements the cohesive design.
The pivot operates on ball bearings, and RAM-LOK locks the blade in place when open. The knife is opened manually using thumb studs on both sides, and the steel clip can be mounted on the right or left side in a tip-up configuration.

Frequently Asked Questions
What makes M390MK steel unique?
M390MK is a variant of M390 steel developed for Microtech in collaboration with Böhler. It retains high corrosion and wear resistance, and its properties have been tailored to the requirements of Microtech knives.
How do you sharpen M390MK?
Diamond sharpening systems and guided sharpening systems, which allow you to maintain a consistent angle, work well for sharpening this steel. Due to the steel’s high wear resistance, sharpening may take longer than with simpler alloys.
How does RAM-LOK work?
RAM-LOK uses a transverse locking element that secures the blade when open. The mechanism is accessible from both sides of the handle, allowing for comfortable operation with either the right or left hand.
How do you maintain the ball bearings?
It’s a good idea to regularly clean the pivot of dust and small debris. If necessary, you can apply a small amount of a light lubricant designed for knife mechanisms.
What does the Bronze Apocalyptic finish with Cerakote coating offer?
The Bronze Apocalyptic finish gives the blade a distinctive, aged look, while the Cerakote coating provides the surface’s bronze color and acts as an additional protective layer against environmental factors.
