This custom-molded sheath allows the Mark I™, Mark I™ Type E, and Mark I™ LE to be carried in the open position like a fixed-blade knife. Re-designed to include dual adjustable tension screws, it holds both manual and automatic versions of the Mark I securely while allowing an immediate combat draw. This high-quality sheath is impervious to the elements and comes equipped with a BLACKHAWK! Mod-U-Lok™ and interface plate that allows full 360-degree mounting on belts and
other hardware and supports attachment to MOLLE gear via our S.T.R.I.K.E.® CQC® Platform (38CL63, sold separately).
