The Tenable Fenrir Button Lock Folding Knife delivers bold styling and dependable everyday performance in a design that’s as satisfying to operate as it is capable in use. Built with clean, aggressive lines and a harpoon-style blade, the Fenrir carries a strong visual presence while maintaining the practical versatility expected from a hardworking EDC folder.
Its 3.45” harpoon blade is crafted from 14C28N stainless steel and finished with a rugged blackwash coating that helps conceal wear while enhancing corrosion resistance. Known for its excellent balance of toughness, edge retention, and easy sharpening, 14C28N performs reliably through the daily cutting tasks most knives see. The blade’s pronounced belly delivers efficient slicing power, while the sharp point allows controlled precision when detail work matters.
Ambidextrous thumb studs provide quick, confident manual deployment, and the Fenrir’s button lock mechanism adds both strength and smooth operation. With a simple press of the push button, the lock disengages and allows the blade to swing freely, creating the smooth, fidget-friendly action enthusiasts enjoy. The mechanism combines dependable lockup with effortless one-handed operation, making the knife both practical and enjoyable to handle.
The handles are constructed from black and red layered G-Mascus G-10, offering impressive durability along with a distinctive pattern that adds depth and visual contrast. The ergonomic shaping provides a secure grip during extended use, while the layered material gives the knife a bold custom-style appearance. An ambidextrous stainless steel pocket clip keeps the Fenrir ready for daily carry, and a lanyard hole offers additional carry options.
Measuring 4.48” closed and weighing 4.23 ounces, the Fenrir strikes a comfortable balance between sturdy construction and pocket-friendly carry.
