So I just got one of Bark River's special hunting knives. I know that Milton Rowland designed this thing for Marbles from BRKT's website, but for the life of me, I can't figure out its functionality. What made this sheath, with its big shield shaped cover, so important? My current theory is that it maybe improves retention, as the cover really tightly presses the mouth of the actual sheath against the knife handle. See the link below for pictures.
