The S.O.G Pentagon FX fixed spear point knife is built for hunters, outdoor workers, and tactical users who need a reliable blade they can trust in the field. With a 4.77" CPM S35VN steel blade finished in black titanium nitride, this fixed-blade knife delivers corrosion resistance and edge retention in a compact, no-nonsense package. The G10 blackout handle provides a secure grip in wet conditions and won't slip when your hands are cold or gloved.
S.O.G engineered the Pentagon FX with a spear-point profile that balances cutting geometry with penetration—useful whether you're processing game, cutting cordage at camp, or handling tactical tasks. The plain edge holds up longer between sharpenings than serrated alternatives, and CPM S35VN is known for taking and keeping a sharp edge. Black titanium nitride coating protects the blade from rust and corrosion while reducing glint in low-light scenarios.
This is a fixed-blade knife, so there's no folding mechanism to fail or maintain. The G10 handle material is lightweight, durable, and engineered to resist temperature swings and moisture—exactly what you want in a tool that lives in a pack or sheath. Whether you're in the backcountry for extended hunts, working around camp, or keeping a dependable blade as part of your gear loadout, the Pentagon FX is designed to perform without fuss.
