The Amphibian is a true Marfione classic dating back over 20 years. It comes from a bygone era when Microtech knives could be both automatic and manual--in one. Here we have the manual version that incorporates Tony's RAM-LOK design with a reversible pocket clip and two thumb studs for a fully ambidextrous knife that sacrifices nothing in any way. It features Bohler's proprietary M390MK steel, available only from Microtech Knives. The knife is similar to the MSI Microtech Standard in terms of size, but when it comes to style, there is no comparison.
