SOG SEAL FX Partially Serrated 4.3" Black Tactical Knife$289.99
Availability: In Stock
The SOG Seal FX Tanto 4.3" tactical fixed blade knife is a purpose-built workhorse for serious users who demand reliability in the field. Born from direct feedback from professional operators, this American-made blade cuts a clean, capable profile whether you're on a tactical mission, managing camp chores, or handling everyday cutting tasks where a fixed blade makes sense. The 4.3-inch tanto blade profile—that distinctive angular point—excels at piercing and controlled slicing; paired with CPM S35VN steel hardened to Rc. 58-60, it holds an edge longer than softer stainless and resists corrosion in wet environments.
What sets the Seal FX apart is its no-nonsense construction. The blade wears a durable black Cerakote finish that shrugs off fingerprints and wear. The handle is 30% glass-reinforced nylon—tough, lightweight, and textured enough to stay put in your grip even when wet or gloved. At 7.2 oz, it won't burden you on a long patrol or backcountry push. The straight edge takes a wicked sharp grind and is easy to maintain in the field with a simple stone or steel.
The Seal FX ships with a kydex sheath in matching black, designed for solid retention and quick deployment from belt, pack, or tactical rig. Kydex is proven to outlast leather in harsh conditions—no rot, no mildew, just consistent performance. The sheath itself is customizable, so you can rig it to suit your carry preference. This is a knife that earns its place in a professional kit, a backcountry pack, or anywhere the task demands a fixed blade you can trust.
