SOG Flash AT Folding Knife 3.45" D2 Steel Partially Serrated

The SOG Flash AT delivers rapid deployment and reliable cutting performance with its spring-assisted opening mechanism and premium D2 tool steel construction. This tactical folding knife combines a 3.45-inch partially serrated blade with ergonomic GRN handle scales for versatile cutting applications in demanding environments.

What Makes This Different

The Flash AT features SOG's Assisted Technology (AT) spring mechanism that provides lightning-fast blade deployment with thumb stud activation. The D2 tool steel blade receives a black titanium nitride coating for enhanced corrosion resistance and reduced glare, while the cryogenic heat treatment process increases edge retention significantly compared to standard stainless steel alternatives. The partially serrated edge configuration handles both precision cutting and aggressive material processing.

Key Features

• Spring-assisted opening with ambidextrous thumb studs for rapid deployment
• 3.45-inch D2 tool steel blade with black TiNi coating and cryogenic treatment
• Partially serrated edge combining straight and serrated cutting surfaces
• Glass-reinforced nylon (GRN) handle with blackout finish for secure grip
• Liner lock mechanism with steel insert for reliable blade lockup
• Deep-carry pocket clip for tip-up or tip-down carry options
• Overall length of 8 inches with 4.55-inch closed length

Field testing demonstrates consistent opening performance across temperature ranges, while the D2 steel maintains sharp edges through extended cutting sessions. The serrated section excels at rope, webbing, and fibrous materials, while the straight edge handles precision tasks and food preparation. The textured GRN scales provide secure grip in wet conditions without adding unnecessary bulk.
