This custom-molded sheath, by BLACKHAWK!, allows the Mark I LE (and pre-2008 versions of the Mark I manual and auto knives) to be carried in the open position like a fixed-blade knife. It is specially designed to hold the knife securely, yet allow for an immediate combat draw. This is a high-quality sheath and is impervious to the elements and comes equipped with mounting hardware so it can be easily attached in a variety of positions to belts or other web gear.
