The Amphibian is a true Marfione classic dating back over 20 years. It’s from a bygone time when Microtech Knives could be both automatics and manuals…in one. What we have here is the manual version incorporating Tony’s own RAM-LOK design with a reversible pocket clip and dual thumb studs for a completely ambidextrous knife that sacrifices nothing in any way. It features the proprietary Bohler M390MK blade steel only available from Microtech Knives. The knife is similar to the MSI Microtech Standard issue in terms of size but when it comes to style, there is no comparison. The Amphibian is one of the coolest tactical knife designs ever and we’re glad to see it back and available to the masses!
