The SOG Pentagon FX Blackout Fixed Blade Knife is built for those who demand performance, reliability, and tactical versatility in one solid package. Whether you're on duty or off-grid, this knife delivers with premium materials and thoughtful design details that make it a trusted companion for everyday carry and demanding field use alike.

At the heart of the Pentagon FX Blackout is a 4.77-inch spear point blade crafted from high-performance CRYO CPM S35VN stainless steel. Known for its edge retention and durability, this steel holds up under pressure and resists wear even in punishing conditions. The blade features a sleek black titanium nitride coating that adds corrosion resistance while reducing reflectivity—ideal for tactical environments. With a plain edge on both sides, it's ready for precision cuts and piercing tasks.

Built with a full tang design, the Pentagon FX Blackout is engineered for strength and balance. The tang is skeletonized to reduce weight without sacrificing durability, providing a better grip and improved control in hand. The removable G-10 handle scales offer a secure, textured hold even in wet conditions, and the all-black finish keeps the aesthetic sleek and low-profile. A lanyard hole offers added utility for attachment or retention.

Carrying the Pentagon FX is just as efficient as using it. The knife comes with a glass-reinforced nylon (GRN) Universal Mounting System (UMS) sheath that includes a low-profile belt clip for convenient on-body carry. Whether you're securing it to a vest, belt, or pack, the sheath offers fast access and dependable retention.

Measuring 9.93 inches overall and weighing just 6.5 ounces, the Pentagon FX Blackout is well-balanced and purpose-built for users who need a reliable edge that doesn't weigh them down. From field work to everyday tasks, it's made to perform when it counts.

The Pentagon FX Blackout stands out as a rugged, professional-grade fixed blade that combines high-end materials with practical design. Whether you're a first responder, service member, or outdoor enthusiast, this knife is up to the task.
