In this review of the SOG Trident AT partially serrated folding knife, the bottom line is simple: this is a tool built for professionals who need a reliable, fast-deploying blade in harsh conditions. The knife stands out for its combination of a cryogenically heat-treated D2 steel blade and a robust AT-XR locking system that gives confidence when working under pressure. Reviewers who value edge retention, a purposeful set of features like a line cutter and glass breaker, and a textured grip will find the Trident AT delivers on practical field performance.

Key Features

The Trident AT is aimed at professional users and serious outdoor enthusiasts who need a dependable folding knife for rescue, tactical, or heavy-duty everyday tasks.
