The SOG Aegis FX Indigo & Yellow is a fixed blade knife designed with real-world performance and everyday utility in mind. Built for those who demand reliability and control from their gear, it delivers strength, comfort, and bold styling in a compact and capable package. Whether you're hitting the trail, working in the yard, or preparing for the unexpected, this knife is engineered to be by your side through it all.
The 3.7-inch drop point blade is crafted from Cryo 4116 Krupp stainless steel—an alloy known for its corrosion resistance, edge retention, and ease of sharpening. The cryogenic heat treatment further enhances its durability, making it ideal for extended outdoor use or demanding utility work. A rugged stonewash finish not only adds a textured, low-glare look, but also helps hide wear over time, keeping the blade looking sharp even after heavy use. Thumb jimping along the spine gives you extra grip and control for detailed cuts or when bearing down on tougher material.
This knife features a full tang construction for maximum strength and reliability. At 8.8 inches overall with a .14-inch blade thickness, it has the backbone to handle serious tasks while still being agile enough for everyday jobs. The weight—just 4.7 ounces—keeps it light in the hand and on the belt, making it an excellent all-day carry for outdoor excursions, work projects, or emergency kits.
The handle is where the Aegis FX really stands out. Crafted from indigo glass-reinforced nylon with an Acid Yellow rubberized overmold, it offers a comfortable, slip-resistant grip that holds up under wet or dirty conditions. The ergonomic shape fits the hand naturally, allowing for secure use with minimal fatigue. Whether you're carving, cutting, or working through camp chores, this handle gives you the confidence and comfort to tackle the task.
A built-in lanyard loop offers carry flexibility and retention options, especially useful in high-movement or wet environments. The included indigo nylon sheath is durable and lightweight, featuring a belt clip for convenient on-body carry. It holds the knife securely while allowing fast, one-handed access, making it just as functional in the field as it is on the jobsite.
From blade to handle to sheath, the SOG Aegis FX Indigo & Yellow is crafted for users who value performance, safety, and design. It’s a no-nonsense fixed blade that’s ready to go wherever you go and perform however you need it to.
