The Invictus-ATC Ti is Terrain 365™’s latest collaboration with Prometheus Design Werx. This compact “ATC” version is built with a rustproof Terravantium™ blade and full titanium throughout the handles, hardware, and pivot. The pivot sits on ceramic bearings with bronze cages, keeping the knife fully non-ferrous, non-magnetic, rustproof, and able to hold an edge for a long time. It is a compact, all-terrain folder made for daily carry on land, in wet environments, and even underwater.

Made with high-quality alloys and designed for real-world use, this knife is strong, smooth to open, and dependable in tough conditions. You never need to worry about rust or pitting, whether it’s exposed to seawater, tropical humidity, or sweat. From backpacking and portaging to exploring old sun-baked cities, deep jungle trails, or remote coastal areas, the Invictus-ATC Ti delivers consistent performance. It is a compact adventure tool built for explorers who need a reliable knife anywhere they go.

We recommend rinsing awith fresh water after any immersion in salt water to remove salt and minerals, ensuring that the action remains smooth and clean.
