The Microtech Knives Halo IV is a premium single-action OTF automatic knife crafted to the brand’s exacting standards. Unlike the dual-action Ultratech, the Halo IV features a single-action mechanism that keeps constant spring tension on the blade during deployment, delivering a sharper, more forceful firing action. Blade retraction is manual, offering complete user control and reinforcing the knife’s mechanical precision.

Measuring 9.25 inches overall with a 3.85-inch blade ground from 0.125-inch stock, the Halo IV achieves an exceptional balance of presence, performance, and carry comfort. With the push of a button, the blade deploys rapidly and locks into place with unwavering reliability.

The streamlined 5.4-inch handle incorporates spine jimping for a secure, confident grip in any condition, while the integrated pocket clip and standard Torx hardware add practical everyday functionality. Weighing just 4.13 ounces, the Halo IV combines aggressive styling with refined engineering, embodying the essence of modern tactical luxury.
