BUILT FOR PROFESSIONALS

The Trident AT is a modern update based on feedback from professional users.

BUILT FOR PERFORMANCE

As the latest update to SOG’s proven Trident design, this newest version is optimized to enhance the user’s capabilities in every critical situation, and the Trident AT opens quickly thanks to its ability to support emergency rescue in high-pressure scenarios.

PURPOSEFUL DESIGN

Every element of the Trident AT was developed for extreme or emergency situations—including fast blade deployment, a line cutter, and a glass breaker—all seamlessly integrated with a highly grippy texture and a durable handle.

SOG’s patented XR Lock with patented Assisted Technology (AT) provides fast one-handed opening and solid lock-up once open. Reliable and powerful, capable of withstanding 1500 pounds of force, the AT-XR Lock provides maximum built-in blade locking security when open and ensures that it opens only when intended.

SAFETY 2.0

SOG worked with users to develop an ambidextrous safety that is as easy as it is fast to use. Designed to be intuitive and to utilize natural hand movements, it means you don’t have to break your grip to operate it. Once open, it locks in place as a thumb backstop. Everything a safety should be.

Our story begins in Vietnam, where members of a highly classified U.S. special operations unit—known as MACV-SOG—carried a unique covert knife into the jungle on secret missions. Several years later, in 1986, that knife inspired a young designer named Spencer Frazer to found SOG Specialty Knives. His mission: to reproduce the original SOG Bowie knife and pay tribute to the special operations unit that created it. What began as a single commemorative model soon became a full line of innovative tools—proven by U.S. special forces and even honored as the knife of choice for the Navy SEALs. Today, SOG knives are carried with confidence into the toughest situations. Forged from tradition, hardened in the field, refined for you.

Whether you protect others or lead an epic hunting expedition, tackle everyday life’s challenges or face your most extreme conditions yet, make your way with SOG.
