Microtech Amphibian FAQ

The Microtech Amphibian returns as a manual folder featuring the heavy-duty RAM-LOK system and a performance-driven recurve blade. This updated version of a Marfione classic offers an ambidextrous design built for rugged, everyday use.

How does the RAM-LOK work on the Microtech Amphibian?
The RAM-LOK is a crossbar-style lock that utilizes a solid metal wedge and a coil spring instead of standard Omega springs to ensure durability. To release the blade on any Microtech Amphibian, you simply pull back the tabs located on both sides of the handle, allowing the blade to swing freely.
What are the benefits of the M390MK steel used in this series?
Bohler M390MK is a proprietary Microtech steel that offers slightly improved edge retention and consistency over standard M390. This high-performance steel is standard across the Microtech Amphibian series, providing exceptional cutting power and corrosion resistance.
Is the Microtech Amphibian suitable for left-handed users?
Yes, the Microtech Amphibian is a fully ambidextrous design featuring a reversible pocket clip and dual-sided lock tabs. Because every control is accessible from either side, it is an excellent choice for both left and right-handed enthusiasts.
What is the advantage of the Amphibian's recurve blade shape?
The recurve blade on the Microtech Amphibian increases the effective length of the sharpened edge for better slicing performance. This geometry is particularly effective for pull cuts, as it pulls the material into the edge for more aggressive cutting power.
How do the handle material options compare?
The Microtech Amphibian series includes variants with fluted G10 or aluminum handles. The G10 versions are slightly lighter and offer a more neutral balance, while the aluminum variants are a bit more handle-heavy and may feel cooler or warmer in the hand depending on the environment.
Is the Microtech Amphibian a manual or automatic knife?
The current Microtech Amphibian models are manual folders equipped with the RAM-LOK system. While earlier versions of this design existed in different formats, the modern series focuses on manual deployment for reliability and accessibility.
