Microtech Marfione Select Halo IV 1150-10MS1 - Single Edge, Stonewashed, Black Aluminum

The Microtech Marfione Select Halo IV is a premium, limited-production out-the-front automatic knife that represents a higher tier of fit, finish, and collectability within the Halo platform. This model features a single-edge blade with a stonewashed finish, offering a clean, low-reflective look paired with strong durability for real-world use. The Halo IV operates on a single-action OTF mechanism, deploying the blade via a top-mounted charging button and requiring manual retraction using the included charging handle—an intentional design that prioritizes strength and mechanical simplicity.

The handle is constructed from black anodized aluminum, delivering a lightweight yet rigid chassis with a streamlined, purpose-built profile. As part of the Marfione Select line, this version emphasizes upgraded finishing details, tighter tolerances, and small-batch production, often accompanied by premium packaging and documentation. With its larger format, distinctive deployment system, and elevated build quality, the Halo IV stands as both a functional automatic knife and a highly collectible piece within Microtech’s lineup.
