The Microtech Amphibian Mini RAM-LOK 137MRL-10FLMS1 is a compact folding knife designed by Tony Marfione, featuring a M390MK steel blade and a milled titanium handle. The model retains the distinctive Amphibian design, featuring a RAM-LOK lock, a ball-bearing pivot, and thumb studs on both sides.
The 82.55 mm blade features a Clip Point profile, a hollow grind, and a stonewashed finish. The gray titanium handle with a milled surface is complemented by a brown titanium backspacer and a double-sided titanium tip-up clip.
M390MK – steel developed for Microtech
The blade is made of M390MK steel, a variant of M390 developed for Microtech in collaboration with Böhler. The material offers high resistance to wear and corrosion, well suited to the demands of modern premium-class folding knives.
Clip Point, hollow grind, and stonewashed
The Clip Point profile provides a distinct tip and good control during precision work. The hollow grind supports efficient cutting, and the stonewashed finish minimizes the appearance of minor signs of wear.
Fluted Titanium and RAM-LOK
The handle is made of titanium with a gray finish and features the distinctive Fluted milling pattern. The bronze titanium backspacer adds a contrasting accent to the design.
The pivot operates on ball bearings, and RAM-LOK locks the blade in place when open. The knife opens manually using thumb studs on both sides, and the titanium 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 developed for Microtech in collaboration with Böhler, designed for high resistance to wear and corrosion.
How do you sharpen M390MK?
Diamond sharpening systems and guided sharpening systems work well for this, as they make it easier to maintain a consistent edge angle.
How does RAM-LOK work?
RAM-LOK uses a transverse locking element that secures the blade when open and allows for comfortable operation from both sides of the handle.
How do you maintain the ball bearings?
It’s a good idea to regularly clean the pivot of dust and dirt, and apply a small amount of light lubricant as needed.
What are the benefits of fluted milling on a titanium handle?
The milled surface increases the grip’s texture and gives the Handle a more technical, distinctive look.
