The Microtech Marfione Select Halo IV OTF Automatic Knife marks the return of one of the most iconic single-action out-the-front designs ever produced. Built with precision and purpose, the Halo IV delivers the raw speed and power the Halo series is known for, making it one of the fastest deploying automatic knives available.

Featuring a 3.875-inch clip point blade crafted from M390MK stainless steel, this knife offers exceptional edge retention, corrosion resistance, and cutting performance. The stonewashed finish enhances durability while giving the blade a rugged, refined appearance.

What sets this Marfione Select version apart is the integrated see-through spine, allowing you to visually confirm blade lockup inside the handle. The long, slim profile provides excellent control, while the single-action OTF mechanism delivers powerful, deliberate deployment with unmatched authority.

The handle is constructed from hardcoat anodized aluminum alloy, offering a lightweight yet durable build. Paired with titanium hardware and pocket clip, this knife reflects Microtech’s highest level of craftsmanship and engineering.

This is not just an automatic knife—it’s a collector-grade Marfione Select piece that showcases Microtech at its most refined, mechanical, and iconic.
