The Halo IV from Anthony and Sean Marfione is one of those iconic figures in the out the front auto realm. Based on the original Halo, the large statured Halo IV is alert and aggressive. Per typical Marfione style, these Dark Matter Halo IV's are not only undeniably attractive, but also constructed of high end components such as M390 and aircraft alloy.  Tall, dark and handsome, the blade on this piece is an incredibly powerful single action jolt.

Brand new directly from Marfione Customs.

The Blade: At nearly 4" long, the powerful Halo IV blade has been composed of M390 stainless steel and recived a Marfione dubbed Dark Matter finish - acid washed and tumbled grinds with satin flats. This straight edge blade fires bia an easy press of the button on the front of the handle. It's single action meaning it will need recocked after each deployment. Simply push the button the handle and pull back on the retraction tab located at the bottom.

The Handle: Light and slender for its size, the aircraft alloy handle has been Mil-Spec Anodized black to compliment the blade. Jimping has been strategically placed in several areas around the handle to insure a solid grip on the otherwise smooth alloy surface including oversized scallops along the spine allowing a peak at the internal workings. Marfione proprietary hardware has been anodized to a sexy purple haze to accent the custom machined titanium pocket clip with ball bearing retention. Otherwise sterile, when fully retracted, you will find the Marfione custom dagger logo and A. Marfione 09/2017, Halo IV U.S.A on the retraction tab.

The Sheath: Includes a custom molded kydex carry sheath with carbon fiber check pattern. Allows for attachment to pocket loop via lanyard and clip while also cloaking the button and blade from accidental firing.

This one ships in a display box with microfiber baggie and cloth, zipper pouch and signed Certficate of Authenticity plate.
