SOG Pentagon FX Covert – 3.41" Fixed Blade, Spear Point, Plain Edge
Black Titanium Nitride (TiNi) Cryo CPM S35VN Blade • G10 Flat Dark Earth Handle
Model: SOG17610457 • UPC: 729857011532
Designed for low-profile carry and high performance, the SOG Pentagon FX Covert (3.41") blends premium materials with a compact, mission-focused form. Its 3.41-inch spear-point, plain-edge blade is crafted from CPM S35VN—a top-tier particle metallurgy stainless renowned for long edge life, toughness, and corrosion resistance. SOG then takes it further with a cryo treatment that refines the steel’s microstructure for enhanced edge stability, and a stealthy Black Titanium Nitride (TiNi) finish that adds abrasion resistance while reducing glare. A textured G10 handle in Flat Dark Earth (FDE) locks in your grip with palm-filling ergonomics and confident traction—even in wet or gloved conditions.
Whether you’re building out a duty kit, adding a compact fixed blade to your overlanding loadout, or upgrading your everyday utility, the Pentagon FX Covert delivers precision, durability, and discreet carry in equal measure.
Why the Pentagon FX Covert Stands Out
Cryo-Treated CPM S35VN Steel
Powder metallurgy stainless enriched with niobium & vanadium carbides for exceptional edge retention and chip resistance. SOG’s cryo process improves hardness uniformity and edge stability for hard daily use.
Black TiNi Protective Finish
The Titanium Nitride coating adds abrasion and corrosion resistance while keeping reflections down—ideal for covert or professional environments.
Spear-Point Precision, Plain-Edge Control
A symmetrical spear point centers the tip for stable piercing and fine detail work. The straight (plain) edge makes clean, predictable cuts and simplifies maintenance.
FDE G10 Ergonomics
G10 composite scales in Flat Dark Earth are tough, dimensionally stable, and aggressively textured—offering a secure, all-weather grip without added bulk.
Compact, Duty-Ready Size
At 3.41 inches of blade length, the Pentagon FX Covert balances carry comfort with serious utility, fitting easily into belts, packs, chest rigs, or vehicle kits.
Note: Always follow local laws regarding knife carry, blade length, and concealment.

Performance You’ll Notice
Long-Running Sharpness
S35VN maintains a working edge far longer than common stainless steels, so you sharpen less and get more done—cardboard, cordage, webbing, banding, and more.
Confident Tip Control
The spear-point geometry balances strength and precision for stable punctures, clean scoring, and careful detail cuts.
Low-Glare Durability
Black TiNi both shields the blade and reduces visual signature, helping it stay discreet in bright or reflective environments.
Locked-In Grip
Textured FDE G10 plus subtle jimping promote a no-slip hold in rain, sweat, or gloves—with a neutral, hand-filling feel for long sessions.
Ideal Use Cases
Duty & Field: Cutting zip ties, cordage, plastic strapping, webbing; tip-precise scoring.
Overlanding & Camping: Food prep, notching, paracord work, tent/strap trimming, feather sticks.
Rescue/Utility: Robust fixed blade with quick deployment and simple, pivot-free cleanup.
Everyday Carry: Compact footprint, fixed-blade reliability, low-glare profile.
Carry & Setup Tips
Mounting Options: Pair with your preferred belt/pack attachment to position the knife vertically or with a slight cant for a smooth draw.
Retention Check: Ensure your chosen carry solution secures the blade yet releases cleanly; adjust hardware for tension as needed.
Glove Drill: Practice draw and re-sheath (or stow) motions with gloves to build real-world muscle memory.
Care & Maintenance
Clean & Dry: Rinse after exposure to moisture, salt, or acidic foods; dry thoroughly to preserve the edge.
Sharpening: Use ceramic or diamond stones with light, consistent strokes; S35VN rewards steady angles. Finish with a quick strop.
Protective Film: Although corrosion-resistant, a thin coat of oil on the cutting edge helps in humid or marine environments.
Hardware Check: Periodically snug handle fasteners and carry-system hardware after heavy use.
Frequently Asked Questions
Q: What advantages does Cryo CPM S35VN offer?
A: It combines excellent edge retention, toughness, and corrosion resistance. Cryogenic treatment improves microstructure for better edge stability under real-world loads.
Q: Is the edge fully plain?
A: Yes—the Pentagon FX Covert in this configuration features a straight (plain) edge for clean cuts and easy upkeep.
Q: Why choose TiNi over a basic coated blade?
A: Titanium Nitride offers superior abrasion resistance and low reflectivity versus many standard coatings, extending both performance and appearance.
Q: How does G10 perform when wet?
A: G10 maintains traction and dimensional stability in wet, hot, or cold conditions; the textured FDE scales enhance grip security.
Q: Is the 3.41" length practical for EDC?
A: Absolutely—this size balances compact carry with enough blade for daily utility and field tasks.
