The Tenable Fenrir Button Lock Folding Knife takes an already aggressive EDC platform and pushes it into full-on attitude with an Undead-themed design that stands out instantly. A funky graffiti-style zombie head graphic is worked into the visual theme, giving the knife a street-art edge that feels bold, chaotic, and fun while still backed by serious cutting performance.
The 3.45” harpoon blade is crafted from 14C28N stainless steel and finished in a rugged blackwash that helps hide wear and boosts corrosion resistance. Known for its strong balance of toughness, edge retention, and easy sharpening, 14C28N is a dependable steel for everyday carry use. The blade’s wide belly makes slicing smooth and efficient, while the sharp tip delivers precise control for detail work and quick utility cuts.
Ambidextrous thumb studs allow fast manual deployment, and the push button lock adds a smooth, fidget-friendly experience that makes the Fenrir especially satisfying to operate. Pressing the button disengages the lock cleanly, allowing the blade to swing freely with controlled action. It’s a design that blends secure lockup with playful, tactile operation.
The handles are built from purple G-10 and feature an Undead graffiti-style zombie head motif integrated into the design, giving the knife a loud, expressive personality without sacrificing durability. The textured G-10 provides a secure grip, while the ergonomic shaping keeps handling comfortable during extended use. The vivid purple finish enhances the artwork and makes the knife instantly recognizable.
An ambidextrous stainless steel pocket clip offers convenient carry options, and a lanyard hole adds versatility. Measuring 4.48” closed and weighing 4.23 ounces, the Fenrir stays practical for everyday pocket carry while still delivering substantial feel in hand.
