Terrain 365

Terrain 365 Knives is a cutting-edge knife brand co-founded by TAD Gear (Triple Aught Design) and knifemaker Patrick Ma, known for pioneering rust-proof, terrain-proof blades built for extreme outdoor and marine environments. Every Terrain 365 knife is designed to thrive in any condition—land, sea, or air—thanks to their exclusive use of dendritic cobalt and other non-ferrous, non-magnetic materials. Ideal for adventurers, divers, survivalists, and tactical users, these knives redefine what durability means in the wild.

Terrain 365: Rustproof Performance for Every Environment

What sets Terrain 365 apart is their use of proprietary Terravantium™—a cobalt-based dendritic alloy that offers edge retention similar to premium steels but with zero iron content. That means no rust, no corrosion, and no magnetic signature—perfect for maritime use, jungle ops, and survival kits. From folding knives to fixed blades, every model is designed with practical outdoor and EDC applications in mind, while remaining lightweight and fully field-ready.
