The S.O.G Trident AT is a tactical folding knife built for users who need speed and reliability in the field. With its 3.70" Cryo D2 steel blade, ambidextrous AT-XR lock, and integrated utility tools, this is a serious everyday carry for hunters, first responders, and outdoor professionals who demand one-handed deployment without compromise.
S.O.G's Assisted Technology delivers a fast, confident open with solid lockup. The AT-XR mechanism is ambidextrous by design — the safety lever works equally well for left and right-handed users, and it's intuitive enough to manipulate even under stress. The blade itself is D2 steel treated cryogenically to S.O.G's specifications, giving you edge retention and corrosion resistance in a high-carbon platform that holds up to real use.
Beyond the blade, the Trident AT includes a line cutter for cutting cord and webbing without dulling your primary edge, plus a glass breaker for emergency situations. The olive drab handle with FDE accents fits naturally in hand and won't draw attention in professional or tactical settings. This is the refined version of a field-proven design — S.O.G refined it based on direct feedback from users who use knives for work, not just carry.

Frequently Asked Questions
Is the Trident AT truly ambidextrous?
Yes. The AT-XR safety lever and lock mechanism work the same for both left and right-handed users, so you're not forced to adapt to a right-handed design.
What's the difference between the AT-XR lock and a standard assisted opener?
S.O.G's AT-XR combines ambidextrous safety with rapid assisted opening and a positive lockup once deployed. The spine-mounted safety system adds an extra layer of secure operation.
What is D2 steel and why cryogenic treatment?
D2 is a high-carbon tool steel known for excellent edge retention and corrosion resistance. S.O.G cryogenically heat-treats it to its own specifications to optimize hardness and toughness for demanding field conditions.
Does the knife come with the line cutter and glass breaker?
Yes, both are integrated into the blade and handle design — no additional parts needed.
