SOG Aegis AT 3.13" Tanto Folding Knife D2 Steel Black TiNi

The SOG Aegis AT delivers precision cutting performance with its 3.13-inch tanto blade crafted from premium D2 tool steel. This folding knife combines tactical functionality with everyday carry convenience through advanced materials and ergonomic design. The black TiNi coating provides superior corrosion resistance while maintaining the blade's razor-sharp edge.

What Makes This Different

The Aegis AT features cryogenically treated D2 steel that undergoes sub-zero tempering for enhanced grain structure and edge retention. Unlike standard stainless steel folders, the D2 composition delivers exceptional hardness ratings between 60-62 HRC while maintaining toughness for demanding cutting tasks. The black Titanium Nitride coating adds a protective barrier that resists wear and environmental damage far beyond conventional finishes.

Key Features

• 3.13-inch tanto blade with cryogenically treated D2 tool steel construction
• Black TiNi (Titanium Nitride) coating for corrosion and wear resistance
• Glass Reinforced Nylon handle in rescue red with indigo accent details
• Assisted opening mechanism with ambidextrous thumb studs
• Liner lock system with steel lock bar for secure blade retention
• Pocket clip for tip-up or tip-down carry configurations

The tanto point geometry excels in piercing applications while the flat grind profile maintains cutting efficiency across the entire edge. Field testing demonstrates consistent performance in rope cutting, cardboard breakdown, and precision tasks where blade control matters. The GRN handle material provides secure grip even when wet, making this knife suitable for outdoor work, emergency response, and professional applications where reliability cannot be compromised.
