0,00 €Microtech Amphibian Mini RAM-LOK S/E Marfione Select Nebula Green Slab Side Titanium, Purple Bksp, Stonewashed M390MK by Tony Marfione – a compact folding knife with a titanium handle
The Microtech Amphibian Mini RAM-LOK 137MRL-10MS17 combines a compact design with the distinctive finish typical of the Marfione Select series. The M390MK steel Drop Point blade features a hollow grind and a stonewashed finish, while the titanium handle is finished in Nebula Green and paired with a purple backspacer.
The model has a total length of 196.09 mm, and the blade itself measures 82.55 mm. This makes it a comfortable size for everyday carry while still being a fully-fledged utility folder. RAM-LOK, ball bearings, thumb studs on both sides, and a reversible clip ensure symmetrical operation of the entire mechanism.
M390MK – High Edge Resistance and Durability
M390MK offers high corrosion resistance, excellent edge retention, and high abrasion resistance. In a folding knife intended for regular use, this reduces the frequency of sharpening and maintains good edge performance over a long period of time.
Drop Point and Hollow – Functional Geometry
Drop Point provides a well-controlled tip and a smooth cutting edge, making it suitable for a wide range of tasks. The Hollow grind supports efficient cutting and allows for a relatively thin geometry in the lower part of the blade.
Stonewashed – a subdued contrast to Nebula Green
The blade features a stonewashed finish, which creates a matte, slightly irregular surface. In this version, it provides a calm backdrop for the more striking Nebula Green handle and purple accents, ensuring the overall design remains bold yet visually balanced.
Nebula Green Slab Side Titanium
The handle is made of titanium and finished in the Nebula Green color scheme. The Slab Side variant features simpler grips, allowing the color and contrast with the purple backspacer to take center stage. Titanium provides high rigidity, corrosion resistance, and durability suitable for everyday carry.
RAM-LOK – ambidextrous operation
RAM-LOK allows you to release the lock from either side of the Handle. This feature works well with the ambidextrous thumb studs and the reversible clip, making the knife comfortable for both right- and left-handed users.
Ball Bearings and Manual Opening
The pivot axis operates on ball bearings, which ensure smooth opening and closing of the blade. The knife remains fully manual, and double-sided thumb studs are used for opening.
Why Choose the Microtech Amphibian Mini RAM-LOK 137MRL-10MS17?
This is the model for users who want to combine the functional RAM-LOK platform with a more unique, collector-oriented design. Nebula Green Titanium, a purple backspacer, M390MK, and a stonewashed finish create a distinctive configuration that retains all the practical advantages of the compact Amphibian Mini.
