The used SOG Pentagon FX Covert was designed as a next-level solution for discreet fixed blade carry. Compact yet capable, it features a double-edged, full-tang CRYO CPM-S35VN stainless steel blade with a tough black titanium nitride finish. The removable textured G10 handles offer excellent grip and can be easily detached for an even slimmer, lighter profile — ideal for truly covert operations.
 
The Pentagon FX Covert includes a minimalist GRN sheath that's compatible with SOG’s innovative Universal Mounting System. Whether you prefer belt, MOLLE, adhesive Velcro, or custom setups, this system gives you ultimate flexibility in how you carry. Despite its modest size, the Pentagon FX Covert delivers serious performance and innovation.
 
This used knife may show minor signs of carry or handling but remains fully functional and ready for reliable service.
