Titanium-Coated S35VN Reverse Tanto Blade - American Walnut G10 Inlay

Developed in collaboration with Zastava Arms USA, this knife draws inspiration from classic rifle design—clean lines, rugged materials, and a focus on functional precision.

A smooth button‑lock system ensures controlled deployment and solid lockup, reinforcing the knife’s deliberate, capable feel.

At just 2.64 oz, the F4 Echo is remarkably light yet built with premium materials that stand up to real‑world use. Whether you’re on the job, on the range, or simply want a refined everyday tool, the F4 Echo delivers a modern blend of strength, precision, and unmistakable character.
