Let’s Talk About SOG Specialty Knives & Tools Pentagon Fx – Fde
The SOG Specialty Knives & Tools Pentagon Fx – Fde is a folding knife designed as a direct descendant of SOG’s renowned fixed-blade Pentagon series. This knife attempts to bridge the gap between tactical fixed blades and the convenience of a folding knife. Its CPM S35VN steel blade and robust construction immediately caught my eye, as did its Flat Dark Earth (FDE) finish.
I needed a reliable EDC (Everyday Carry) knife that could handle demanding tasks while remaining relatively discreet. Many folding knives feel flimsy, so the promise of Pentagon-level durability in a folding package was extremely appealing. This knife was chosen to fill a need for a robust tool with a manageable size.
Upon unboxing the SOG Specialty Knives & Tools Pentagon Fx – Fde, the first thing I noticed was its substantial feel. The weight (6.5 oz) is reassuring, and the G10 handle scales provide a solid, confident grip. The FDE finish on the blade is evenly applied and adds a tactical aesthetic.
Compared to my Benchmade Griptilian and Spyderco Paramilitary 2, the Pentagon Fx feels like a different animal. While the others excel in slicing and everyday tasks, the Pentagon Fx seems built for more rigorous use. I picked the Pentagon Fx for its reputation for strength and its dagger-like blade shape, ideal for certain tactical applications.
My initial impression was excitement tempered with a bit of curiosity. The SOG Specialty Knives & Tools Pentagon Fx – Fde certainly looked the part of a heavy-duty folder, but I was eager to see if it could truly live up to the Pentagon name. Time would tell if it was more than just a pretty, albeit tactical, face.
Real-World Testing: Putting SOG Specialty Knives & Tools Pentagon Fx – Fde to the Test
First Use Experience
I first tested the SOG Specialty Knives & Tools Pentagon Fx – Fde during a weekend camping trip in the nearby mountains. I primarily used it for tasks like preparing kindling, cutting rope, and food preparation. The knife felt secure in my hand, even when wet from a light rain.
The CPM S35VN blade sliced through wood with ease and the point proved useful for creating feather sticks. After some initial cardboard slicing, the knife needed stropping to get its hair shaving edge back, but it performed admirably. I did find that the handle, while grippy, could become a bit abrasive during extended use without gloves.
No major issues arose during its initial use.
Extended Use & Reliability
After several months of use, the SOG Specialty Knives & Tools Pentagon Fx – Fde has proven to be a reliable tool. It has accompanied me on several hiking trips, range days, and even seen some light-duty tasks around the house. There are no signs of blade play or loosening of the handle scales.
The FDE blade finish has held up well, with only minor scratches appearing after being used in the field. Cleaning is straightforward; a quick wipe down with a damp cloth and occasional lubrication of the pivot point is all it needs. Overall, the durability of this knife is very impressive.
Compared to other folding knives I’ve owned, the Pentagon Fx excels in situations where toughness is paramount. The blade steel is durable, though perhaps not the easiest to sharpen in the field. The overall design of the Pentagon Fx instills confidence, knowing that it can withstand pretty rigorous use.
