SOG Trident Ambidextrous Tanto Folding Knife | Heat-Treated CRYO D2 Steel Blade

The SOG Trident AT Tanto Pocket Folding Knife is designed for professional users, featuring rapid assisted opening with SOG's innovative ambidextrous AT-XR Lock, integrated line cutter, and glass breaker. It is also easy to carry and has a highly functional 3.75" cryogenically heat-treated D2 stainless steel blade. The powerful AT-XR locking mechanism includes a built-in blade locking safety and spine-mounted safety system, making it the next evolution of the field-proven Trident pocket knife.

SOG's story begins in Vietnam, where the highly classified US special ops unit MACV-SOG carried a unique combat knife into covert missions. In 1986, this knife inspired young designer Spencer Frazer to found SOG Specialty Knives with the mission of reproducing the original SOG Bowie knife and paying tribute to the special ops unit that created it. What started as a single commemorative model became a full line of innovative tools, field-proven by US Special Forces and honored as the Navy SEAL knife of choice. Today, SOG knives are carried with confidence into the most demanding situations, forged out of tradition, hardened in the field, and honed for you.

The Trident AT Tanto Folding Knife is a modern update based on the feedback from professional users and is made to hold up in the harshest conditions, balancing purposeful design with heavy-duty performance and reliability. Every element of the Trident AT folding knife, including the fast blade open, line cutter, and glass breaker, has been developed for extreme or emergency situations, all seamlessly integrated with a high-grip textured and durable handle.

The AT-XR Lock technology from SOG delivers fast one-handed open and solid lock-up once open, able to withstand 1500 pounds of force, and provides built-in blade locking security when open. The safety 2.0 design is intuitive and utilizes natural hand movements, ensuring fast deployment, even when wearing gloves. The cryo D2 steel blade is a versatile high-carbon tool steel that is cryogenically heat-treated to SOG's unique performance specifications, providing the ideal combination of edge retention and durability for long term use with ease of maintenance.
