SOG Aegis AT Folding Knife 3.13" D2 Steel Black TiNi Blade GRN Handle

The SOG Aegis AT delivers reliable cutting performance with its 3.13-inch drop point blade crafted from premium D2 tool steel. This folding knife combines advanced metallurgy with ergonomic design to create a versatile everyday carry option that excels in demanding applications.

What Makes This Different

The Aegis AT features a black titanium nitride (TiNi) coating applied through cryogenic treatment, significantly increasing surface hardness and corrosion resistance compared to standard coatings. The D2 steel blade maintains a sharp edge longer than most stainless options while offering superior wear resistance. SOG's precision manufacturing ensures consistent lockup and smooth operation through thousands of cycles.

Key Features

• 3.13-inch drop point blade in premium D2 tool steel with 58-60 HRC hardness
• Black titanium nitride coating with cryogenic treatment for enhanced durability

Field testing demonstrates the Aegis AT's capability across utility tasks, outdoor activities, and professional applications. The D2 steel composition excels in cutting cardboard, rope, and wood materials while maintaining edge geometry. The TiNi coating resists scratches and reduces friction during cutting operations, even in humid conditions.
