Core Edge – 0331 – Echo – OTF Auto – CPM MagnaCut Blasted Tanto – Aluminum – Natural

The Core Edge 0331 Echo OTF is a precision-engineered out-the-front automatic knife that blends modern materials with a bold, performance-driven design. Built in the USA, this model reflects a commitment to durability, reliability, and clean mechanical action, making it a compelling option for both collectors and everyday carry enthusiasts who demand high-end performance. At the heart of the Echo is its double-edge tanto blade crafted from premium CPM MagnaCut steel. Known for its exceptional balance of edge retention, corrosion resistance, and toughness, MagnaCut elevates this knife into a top-tier category for cutting performance. The blade features a blasted finish with satin flats, creating a visually striking contrast while also reducing glare and enhancing wear resistance over time. The double-edge tanto profile offers excellent piercing capability combined with reinforced tip strength, making it both functional and aggressive in appearance. The handle is machined from 6061-T6 aluminum, a lightweight yet robust material widely respected in aerospace and tactical applications. The chassis incorporates a distinctive honeycomb milling pattern across flat front and back surfaces, improving grip texture while reducing overall weight. A Type III hardcoat anodized finish further enhances durability, providing resistance against scratches, wear, and environmental exposure. Operationally, the Echo OTF delivers smooth, consistent deployment and retraction through its precision internal mechanism. Stainless steel hardware and a matching stainless pocket clip ensure long-term reliability and corrosion resistance while maintaining a cohesive, rugged aesthetic.
