The Mark 3 MOD 0 knife and sheath: 1) has a sharpened and clip point of one side of the blade; 2) has a saw on the other side of the blade; 3) has a hand guard that prevents the hand from going forward on to the blade in a stabbing motion as well as the object from coming on to the hand; 4) a butt cap that resembles a hammer's face and can be used for such; and 5) by far the best sheath for holding a knife in place, one can without the snap in place and in a pitching motion throwing forward but holding onto the sheath not dislodge the knife from the sheath.
