Demko Fixed Blade Knives
Demko's fixed blade lineup applies the same function-first design philosophy found in the folder catalog — but without a lock mechanism to engineer around, the focus shifts entirely to blade geometry, steel selection, and sheath integration. The two current models, the Armiger 4 and the FreeReign, cover different size classes and use cases while sharing a common approach: full tang construction, tough steels, and sheaths built for real carry rather than drawer storage.
The Armiger 4 is a compact fixed blade with a 4-inch blade, 8.4375 inches overall, and a weight around 4.4 ounces. It's a full tang design with TPR (thermal plastic rubber) handles that provide a reliable grip in wet or dirty conditions. The standard models use German 80CrV2 steel with a powder-coated finish — a carbon tool steel with strong edge retention that sharpens easily in the field. The USA-made variants step up to CPM-3V with a multi-layer camouflage cerakote finish, adding significantly more toughness and impact resistance for heavy-duty field work. Blade profiles include Clip Point, Tanto, and Spear Point, with serrated options available on select configurations.
The FreeReign is a larger platform — 5-inch blade, 10 inches overall, roughly 7.3 ounces. It runs a full-thickness tang with rubberized injection molded handles contoured for extended use. Steel options span three tiers: AUS-10A on the production models, CPM-3V on the mid-range USA-made versions, and CPM MagnaCut at the top — the same next-generation stainless appearing on the AD20 XL. Blade shapes include the Drop Point, Clip Point, and Tanto. The FreeReign's profile sits close to a spear point, with the tip riding just above centerline for a balance of piercing capability and belly for slicing work.
Both models ship with Demko's proprietary injection molded nylon hybrid sheaths. The sheath core uses a non-glass nylon material specifically designed to avoid dulling the blade during draw and sheath cycles — a detail that matters when you're using the knife daily rather than displaying it. The outer rim is glass-reinforced for rigidity, the assembly breaks down for cleaning, and the slot pattern is MOLLE compatible for modular carry options.
For users who know Demko primarily through the Shark Lock folders like the AD20.5 or Shark Cub, the fixed blade side of the catalog is worth exploring. No lock to think about, no deployment mechanism — just a blade that's ready when you pull it. Browse the full Demko Knives collection to compare across the lineup.
