SOG Pentagon FX 4.77" Blackout Tactical Fixed Blade Knife

The SOG Pentagon FX 4.77" Blackout tactical fixed blade knife is a purpose-built field companion for hunters, outdoorsmen, and anyone who needs a dependable blade in serious situations. This is a working knife—no frills, all capability. The 4.77-inch spear point blade cuts, dresses game, processes firewood, and handles camp chores with equal competence. CPM S35VN steel holds an edge under real use and sharpens without fussing; the black titanium nitride finish resists corrosion and won't flash light at the wrong moment. A G10 handle locks in your grip whether your hands are wet, gloved, or cold, and the design lets you deploy the blade with one hand if the situation demands it.

SOG's Pentagon FX is built for the field, not the display case. Spear point geometry gives you a fine tip for detail work and a robust spine for heavy cuts and leverage. The fixed blade design eliminates the failure modes of folders—nothing to lock, nothing to adjust, nothing to go wrong when you need it most. Whether you're gutting an elk, processing camp meals, or working through rope and cordage, this knife simply does the job.

Comes with a sheath, so you're ready to carry from the moment it arrives. The balance of edge geometry, steel chemistry, and handle ergonomics makes this an honest choice for serious outdoor work, not a sales pitch. If you hunt, camp, fish, or spend serious time in the field, a fixed blade like this deserves a spot in your kit.

Frequently Asked Questions

What kind of work is this fixed blade knife designed for?

The Pentagon FX is built for hunting, field processing, camping, and general outdoor work. The spear point blade excels at both fine detail cuts and heavy-duty chopping and leverage. It's equally at home dressing game, processing firewood, or handling camp tasks.

Why CPM S35VN steel?

CPM S35VN balances edge retention, corrosion resistance, and ease of sharpening—a practical choice for field blades that see real use. It holds an edge through demanding work without requiring specialized equipment to touch up.
