Meet the everyday-carry workhorse that blends fast deployment with rock-solid lockup and modern materials: the SOG Flash AT (Urban Gray). Its 3.45-inch straight back blade is crafted from D2 tool steel for outstanding edge retention and cutting bite, then coated in a stealthy Black TiNi (Titanium Nitride) finish to resist wear and reduce glare. SOG’s AT-XR Lock pairs assisted opening for quick, one-hand deployment with high-strength, ambidextrous lockup you can trust. A lightweight, Urban Gray GRN (glass-reinforced nylon) handle delivers grippy ergonomics without pocket bulk, and a deep-carry pocket clip keeps the knife discreet until it’s time to cut.
From box breakdowns and zip ties to cordage and field chores, the Flash AT (SOG11180541) is the color-matched, mission-ready folder designed to keep up—every day.
Why the Flash AT (Urban Gray) Stands Out
Premium D2 Cutting Performance
The high-carbon D2 tool steel blade offers excellent edge retention and wear resistance, powering through cardboard, banding, nylon webbing, and tough daily materials with fewer touch-ups.
Low-Glare Black TiNi Coating
The Titanium Nitride finish adds abrasion and corrosion resistance while minimizing reflections—ideal for shop, warehouse, and office carry.
AT-XR Lock + Assisted Opening
SOG’s AT-XR mechanism provides ambidextrous, high-strength lockup and a tuned assisted-open for quick, confident one-hand operation—even with gloves or in wet conditions.
Straight Back, Plain-Edge Precision
A straight back profile with a clean, plain edge delivers predictable slicing and easy sharpening, with strong tip control for scoring and detail work.
Lightweight, All-Weather Grip
The Urban Gray GRN handle is textured for traction, resists temperature swings, and won’t weigh down your pocket or pack.
Deep-Carry Discretion
The low-riding clip tucks the Flash AT out of sight yet keeps it instantly accessible for EDC tasks.
Always follow local laws regarding knife carry and blade length.

Performance You’ll Notice
Fast, One-Hand Deployment
The assisted action snaps the blade open authoritatively, locking up with the AT-XR for immediate use—perfect in gloves, rain, or cold.
Long-Running Sharpness
D2 holds a hardworking edge across abrasive materials, so you spend more time cutting and less time on the stones.
Smooth, Controlled Slicing
A plain edge and straight-back geometry give you linear slicing with easy push cuts and a sturdy spine for controlled pressure.
Confidence in Any Grip
Textured GRN scales and neutral ergonomics keep the knife planted in the hand during pull cuts, pierces, and repetitive tasks.
Ideal Use Cases
EDC & Office: Break down boxes, open mailers, trim labels and tape with clean, precise cuts.
Shop & Warehouse: Tackle pallet wrap, plastic strapping, and nylon webbing efficiently.

First-Responder/Utility: Assisted speed and high-strength lock for quick, controlled deployment when seconds matter.
How to Get the Most from Your Flash AT
Practice Deployment: Build muscle memory for safe one-hand opens and controlled closings, including with gloves.
Edge Care: Touch up D2 with ceramic or diamond stones; finish with a light strop to keep it razor keen.
Minimal Lube: A tiny drop at the pivot/lock interface maintains smooth action without attracting debris.
Hardware Check: Periodically snug pocket-clip and body screws after heavy use.
Care & Maintenance
Clean & Dry: Wipe the blade after adhesive-heavy cuts or moisture exposure.
Protect D2: D2 is semi-stainless—apply a thin coat of oil after wet or salty environments, especially at the pivot.
Finish Friendly: Avoid harsh abrasives to preserve the Black TiNi coating.

Q: How strong is the lock?
A: The AT-XR is engineered for high lock strength and repeatable engagement under load, inspiring confidence for daily tasks.
