The Microtech Marfione Select Halo IV marks the triumphant return of one of the most legendary out-the-front automatics ever produced. Revered by collectors and enthusiasts alike, the Halo IV combines unmistakable Marfione styling with blisteringly fast single-action deployment that remains one of the most powerful and satisfying automatic mechanisms ever built.

This Marfione Select edition elevates the Halo platform with premium materials, meticulous machining, and refined finishing throughout. The 3.875-inch M390MK stonewashed tanto blade offers exceptional edge retention, corrosion resistance, and piercing strength while maintaining outstanding cutting performance for everyday utility or collection display.

One of the Halo IV's defining characteristics is its innovative see-through spine construction, allowing you to visually confirm the blade's locked position inside the handle while dramatically showcasing the knife's internal engineering. Combined with its long, slim profile and ergonomic hardcoat anodized aluminum handle, the Halo IV delivers remarkable balance and confident control despite its commanding presence.

Unlike conventional double-action OTFs, the Halo IV utilizes a single-action automatic mechanism that launches the blade with tremendous force. The blade is then manually retracted using the included charging tool, creating a deployment experience that is uniquely mechanical, deliberate, and immensely satisfying.

Finished with a titanium tip-down pocket clip, double vapor blasted stainless hardware, and Tony Marfione's unmistakable design language, the Halo IV represents Microtech craftsmanship at its highest level. Whether destined for a premium collection or carried by those who appreciate legendary automatic knives, the Halo IV remains one of the most iconic OTF designs ever created.
