Representing an evolutionary step in hard-use fixed blades, Pentagon FX is a full-sized knife made for the modern-day warfighter. It features a double-edge CYRO CPM-S35VN full-tang steel blade, removable G10 handles, and a GRN sheath compatible with SOG's next-generation Universal Mounting System. It's fully customizable to meet the demands of various missions and purposefully designed to exceed expectations. Pentagon FX's sheath system isn't the only thing that's adaptable. The handles can also be removed for a slimmer profile. The Pentagon FX comes with multiple accessories from SOG's Universal Mounting System. It allows for a flexible mission-specific set-up, including adjustable sheath retention, secondary retention, mounting angle, mounting method, and combinations of each.
