SOG Trident FX Fixed Blade OD Green 4.2in Plain TiNi Coated Tanto SOG17120357

The SOG Trident FX Fixed Blade Knife in OD Green is a mission-ready tactical knife built for professionals, adventurers, and those who demand uncompromising performance in extreme environments. Whether you’re on the trail, in the field, or preparing for the unexpected, the Trident FX delivers dependable strength, lightweight comfort, and military-grade toughness in a streamlined, modern design. Engineered by SOG—an industry leader in tactical knives and gear since 1986—this fixed blade is a top choice for first responders, survivalists, and tactical gear collectors.

The Trident FX features a 4.2-inch CRYO 4116 stainless steel tanto blade, designed for powerful penetration and reinforced tip strength. This blade shape is ideal for piercing, prying, and slicing through dense materials, making it an excellent companion for tactical missions or rugged field use. The black titanium nitride coating enhances the blade’s durability, adding a layer of corrosion resistance while also minimizing glare—perfect for stealth operations and heavy-duty environments.

Built with a hidden tang construction, the Trident FX offers a slim yet strong profile without compromising structural integrity. The full-length blade is anchored securely within the handle for maximum stability and long-lasting durability. Thumb jimping along the spine adds traction and control for precision cuts or pressure-based tasks, allowing for a secure grip even in wet or slippery conditions.

The olive drab GRN (glass-reinforced nylon) handle is lightweight yet incredibly tough, offering a comfortable, ergonomic grip that won’t weigh you down. Textured for enhanced handling and equipped with a lanyard hole for carry options or retention cords, the handle balances utility and user comfort for high-stress environments. Its subdued OD green color aligns with the Trident’s tactical roots while also offering low-visibility appeal for field applications.

Weighing just 4.5 ounces and measuring 9.4 inches overall, the Trident FX hits the sweet spot between strength and portability. It comes with an olive drab nylon sheath equipped with a practical belt clip for easy attachment to gear, packs, or tactical belts. The sheath’s durable design ensures safe storage and quick access in critical moments, whether you’re on the move or stationed at camp.
