Designed as an evolutionary step in concealed fixed blade knives, Pentagon FX Covert is ideal for discreet carry. It features a double-edge CYRO S35VN full-tang steel blade, removable G10 handles and a minimalist GRN sheath compatible with SOG's next-generation Universal Mounting System. A lot of innovation is in this small package. It's modest in size, but big in capability.

TAKE IT ALL OFF

Require Pentagon FX Covert to be even more minimalist? The handle is easily removed by unfastening the single fastener and sliding the handles off for lighter weight and sleeker profile.

MINIMALIST LOW-VIS SHEATH

Pentagon FX Covert sheath is designed to be flexible: mount it on a belt, in between MOLLE, with adhesive Velcro or as part of SOG’s Universal Mounting System.

FEATURES

A small-format fixed-blade knife with removable G10 handles that can strip down to a lighter and sleeker duty knife.
