Terrain 365™ has partnered up with Prometheus Design Werx to bring you our special technical edition of the Invictus folder design. This variant known as the Invictus-AT (All Terrain) features our Terravantium™ blade, all titanium handles, hardware, and pivot. The pivot bearings are ceramic with bronze cages, making this folder 100% non-ferrous, non-magnetic, rustproof with superlative edge holding characteristics. A truly all terrain-capable utility folder for EDC in any environment anywhere on land or underwater. Precision made, rustproof, and versatile. This is a folder born from purpose driven design in an industrial aesthetic and built with state-of-the art alloys. You'll never have to worry about rust or pitting from getting the Invictus-AT soaking wet by sea water to jungle sweat. From backpacking to portaging, navigating through a remote, sun baked ancient city in a distant land, exploring mysterious ruins deep in a jungle, or a week of epic sets on a hidden break in the South Pacific, this high performance folder is an apex cutting tool for explorers and adventurers. The Terrain 365™ Invictus-AT is a superlative Adventure Tool for All Terrains that you'll never want to explore the world without. We recommend a fresh water rinse after any immersion in salt water to flush out salt and minerals to keep the action smooth and clean.
