The SPD Edition of the Terrain 365 Otter Flip-AT is a fast, flipper action, compact, folder featuring our rustproof, edge-holding Terravantium™ blade. "AT" means this folder is built for "All Terrains" and impervious to rust. Like its animal namesake, this pocket knife is equally at home in the water or on land. Available with PDW exclusive OD Green linen micarta scales and titanium liners.
With a similar profile as the Terrain 365 Otter Slipjoint, the Otter Flip-AT uses a contemporary flipper tab to quickly open the blade and a 100% rustproof, nonferrous, nonmagnetic All Terrain construction with OD Green linen micarta contoured scales, titanium liners, titanium hardware, pocket clip, and ceramic bearings.
What I will first say is that this knife is shockingly light weight. Second, that this flipper really flips. After doing some research, I want to say that although the knife is non-ferrous and does not interfere with a compass, metal detectors detect iron, nickel and COBALT so don't try to walk through a metal detector with it. As far as corrosion resistance, I have no personal knowledge but after significant research I think the descriptions can be trusted. I also personally very much appreciate the design and style. Finally, "they" say the blade is toothy (and it is) but it's also sharp. I've not sharpened mine yet, but I looked at the factory edge through a jeweler's loop and you can actually see that it's toothy. Very interesting knife, great carry option.
