Microtech Amphibian RAM-LOK Manual Folding Knife – 3.875" M390MK Black Apocalyptic Blade, Distressed Fluted Alloy Handle

The Amphibian marks the return of one of Tony Marfione’s most iconic designs—modernized, refined, and built for today’s serious knife users. This latest generation brings back the legendary dual-purpose spirit of the original while embracing Microtech’s proprietary RAM-LOK crossbar mechanism for rock-solid lockup and completely ambidextrous operation.

The 3.875" blade is made from Microtech-exclusive Böhler M390MK, a steel engineered specifically for the brand with elite edge retention, corrosion resistance, and cutting performance far beyond traditional premium steels. The Black Apocalyptic finish gives the blade a rugged, battle-worn aesthetic while reducing glare and wear visibility.

Its 7075-T6 ordnance-grade aluminum frame is deeply fluted and distressed, delivering exceptional rigidity with a purpose-built grip texture that locks into the hand. Dual thumb studs, a reversible titanium pocket clip, and a balanced 9.25" overall length make the Amphibian a powerhouse folder capable of both everyday utility and hard-use field tasks.

This generation stands shoulder-to-shoulder with the MSI in size, but the Amphibian’s styling, ergonomics, and heritage give it a personality all its own. For collectors and operators alike, this is one of the most striking manual folders Microtech has ever produced.
