Microtech Ultratech S/E Gen IV OTF Auto 3.5″ M390MK Serrated Green

This automatic OTF opens with a push of the button and closes with a press of the spine. The 3.5″ blade is stonewash-finished Bohler M390MK stainless—a high-carbon, high-chromium steel that resists corrosion and holds an edge well. The serrated edge handles slicing and cutting tasks where a plain edge might slip. At 5″ closed, it carries compact in a pocket or pack. The OD green aluminum handle is durable and lightweight, with a pocket clip for carry, a lanyard hole for attachment options, and a glass breaker built into the spine for emergency situations.
