SOG Aegis AO Folder Black GRN Handle AUS-8 Black TiNi PS Tanto Point Blade SOG-AE04-BX

The SOG Aegis AO Folder Throwback Edition delivers a proven tactical design refined for modern everyday carry, combining fast assisted-opening performance, durable construction, and versatile cutting power in a dependable, no-nonsense package. Built for users who want speed, strength, and adaptability, this knife brings together classic SOG engineering with practical updates for real-world use.

At the core is a 3.5" blade crafted from AUS-8 stainless steel, a trusted steel known for its balanced performance, offering solid toughness, corrosion resistance, and easy sharpening. Heat treated to an RC hardness of 57-58, it provides consistent edge reliability while remaining simple to maintain over time. The blade is finished in a hardcased black TiNi coating, enhancing wear resistance, reducing glare, and giving the knife a bold, tactical appearance built for hard use environments.

The blade features a versatile geometry that blends a drop point profile with a reinforced tactical edge design, making it capable of handling both precision tasks and heavier cutting demands. The flat grind ensures efficient slicing performance, while the half serrated edge adds extra utility when dealing with rope, cord, webbing, and other fibrous materials. At 0.13" blade thickness, it maintains a strong, durable structure without sacrificing speed or control in hand.

The assisted opening mechanism allows for quick, one-handed deployment, giving you immediate access when needed. The action is smooth and responsive, designed for reliability in high-pressure or everyday situations. Once open, the piston locking mechanism engages securely, holding the blade firmly in place for confident, stable use during demanding tasks.

The handle is constructed from glass-reinforced nylon (FRN), finished in black for a clean, understated tactical look. Lightweight yet highly durable, it provides a secure grip while standing up to daily wear and impact. At 4.75" closed length and 3.1 oz., the Aegis carries easily in pocket or gear without unnecessary bulk, making it ideal for consistent everyday carry.

With an overall length of 8.25", the knife offers a full, controlled grip when deployed while still maintaining a compact carry profile. A reversible deep-carry belt clip allows for flexible, discreet carry options tailored to user preference.

The SOG Aegis AO Folder Throwback Edition combines black TiNi AUS-8 reinforced blade design, black FRN handle, piston lock security, and assisted opening speed in a rugged tactical EDC platform.
