Based on the design of the original SOG-TAC automatic, the TAC XR introduced the ambidextrous XR Lock to this iconic platform. SOG is back again with the next evolution in the TAC AU automatic folder. It retains the XR lock with the addition of a double-action safety that allows for secure carry with fast deployment. A robust construction makes this a popular choice with military, law enforcement and civilian users alike. This Tanto version comes with a black titanium nitride coated D2 tool steel blade and matching 6061-T6 aluminum handle scales.

Brand new, direct from SOG Knives.

Blade: Equipped with a high saber grind and top swedge the D2 Tanto blade offers solid performance balanced with durability. The black TiNi coating is discreetly non-reflective and enhances corrosion resistance, while the plain cutting edge delivers clean slicing action. Pull back the ambidextrous AU-XR Lock for fast automatic deployment.

Handle: Contoured and textured 6061-T6 aluminum handle scales are lightweight and durable with a proud jimped back spacer offering traction and a contoured feel for added comfort. The AU-XR lock can withstand up to 1500 pounds of force, can be operated with either hand and features an integral, double-action safety: center position is ready to deploy, forward position is safety engaged. Pull past the safety detent, and you can deploy from either position.

Carries via a reversible stainless-steel pocket clip.

D2 Tool Steel: Used as a die cutting steel since WW II, D2 offers a good combination of hardness and wear resistance with moderate toughness and stain resistance. High chromium content for a tool steel (10-13%) gives D2 better corrosion resistance than most high carbon steels.
