Its black anodized finish provides a tactical look and enhances corrosion resistance. Machined grooves along the frame improve grip and control, ensuring a firm hold even in wet or gloved conditions.
🧰 Built-In Glass Breaker & Pocket Clip
Practicality meets readiness with a hardened glass breaker integrated into the handle’s base — a critical tool for emergencies, vehicle extractions, or rescue work. The pocket clip keeps the knife secure and accessible for everyday carry, offering a deep, low-profile fit for discreet use.
