SOG Knives

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.

A pretty good knife, but hard to sharpen.
High quality knife, just the right size for easy carry and use in almost any conceivable configuration. A very hard blade which will keep an edge a long time. The Pentagon FX is nicely weighted with a good balance and feel. The Covert version is even more discreet, smaller than the FX yet remains highly effective, perhaps even better at some tasks.SOG Offers free resharpening and guarantees these knives for the lifetime of the owner.

Bad tips
I ordered 2 of these knives and they both came with tip/grind issues. I understand it's difficult to get 4 separate grinds to meet at the tip and form a nice point, but for the price of these knives I expected that problem to be solved. Also, the secondary bevels seem to be rounded/convexed in a way that makes sharpening on a flat stone challenging. I'm rather disappointed.

3rd try knifecenter......will you post??
This knife is terrible, blade so dull it won't cut through air. SOG has horrific QC issues as most knife enthusiasts know already. I'd love to see a well executed knife of similar design that wasn't complete garbage.
