Tenable Fenrir Custom Fleet: Sparrow Knife Design

The Tenable Fenrir Custom Fleet: Sparrow Knife Design Across 3 Lock Systems & 50+ Flavors

Listen up, you beautiful horde of crayon-vampires, paste-eaters, and tactical window-lickers. If your current pocket setup looks like everyone else’s boring, flat-gray, sanitized corporate knife, your EDC rotation is running on pure failure. Meet the Tenable Fenrir Platform, drafted by Greg Schob of Sparrow Knife Design. This isn't some dainty mail-opener designed for an office softie; it’s an aggressive, sweeping, multi-deployment tactical war-cleaver built for the "C.E.W.L. Offender" who wants severe workbench utility paired with enough finish options to make your head spin.

Tenable took Sparrow’s legendary ergonomics and unleashed it across three separate locking mechanisms (Top Liner Lock, Plunge Button Lock, and Crossbar Lock), dropping them in everything from hard-working D2 and Sandvik 14C28N to screaming Nitro-V super-steel and patterned Damascus.

Pick your lock layout, select your scale armor, and stop carrying gas-station garbage.

The Sharp & Salty Details (Shared Fenrir Architecture)

• Greg Schob (Sparrow Knife Design) DNA: Engineered with Schob’s signature ergonomic sweep—delivering an aggressive, deep-bellied harpoon-modified drop point profile that sinks into tough shop cuts, zip-ties, rubber hoses, and packaging with surgical leverage.

• Triple-Deployment Ready: Most configurations feature an extended front/top flipper tab paired with dual thumb studs, riding on silky caged ceramic ball bearings for zero-slop mechanical deployment.

• Premium Metallurgy Options: Forged from high-hardness Nitro-V (corrosion-proof edge retention), cryo-treated Sandvik 14C28N (toughness and easy stropping), high-wear D2 tool steel, or pattern-welded Damascus.

• Engineered Handle Real Estate: Contoured finger choil and intentional spine jimping provide a locked-in, non-slip four-finger grip that completely eliminates slippage when your hands are soaked in cutting fluid, motor oil, or sweat.

• Deep-Carry Hardware: Sturdy, low-profile pocket clip set up for locked-in tip-up carry to delete pocket drag from your daily routine.

The Tenable Fenrir Series pulls zero punches, wipes out boring corporate cutlery, and puts genuine custom-tier knife design directly on your bench. Stop acting like a mouth-breathing bystander with a dull utility knife—pick your lock, select your blade-and-scale flavor, and drop a Fenrir straight into your lineup.
