The Halo 4 is noticeably smaller than its predecessor, the Halo V. Its size is certainly felt in hand and results in a much more wield-able knife. The thin handle has finger grooves top and bottom along with judicious notches for grip, and from above the knife shows thoughtful symmetry. Its stainless steel draw bar utilizes an integrated spring detent for seamless performance without traditional means. Action on the Halo IV has the kick you crave and solid lock-up. This Marfione Custom Halo IV has a hollow, hand ground M390 steel blade with a black DLC polished finish. The handle is hard coat anodized 6061-T6 aluminum with black DLC coated hardware and Begg-style pocket clip. Includes custom fitted sheath. Model information, date of production, and the Marfione Dagger are marked on the draw bar.
