Microtech Halo IV - Hardcoat Anodized Black Handle - Stonewashed Blade

The Microtech Halo IV S/E Marfione Select OTF Automatic Knife is a bold return to one of the most iconic out-the-front designs ever created—refined with premium materials, modern engineering, and unmistakable Marfione craftsmanship. Built for collectors and serious enthusiasts alike, this knife delivers explosive single-action deployment with authority, speed, and precision that still sets the benchmark in the OTF world.
