An obviously carried and well used but very early production sheath for the model 24 guardian. This type sheath was intended to be worn around the neck, back of sheath facing outward, with a tie tac secured to the leather flap sewn to the back of the sheath. A rubber band or O-ring holds the knife in position. An unbuttoned shirt button under the tie permitted the wearer easy access by fiegning a scratch to the chest. This was Bo's preferred method. Sheath is marked only with the number "24" at the top of the front side. Completely serviceable, but well used. Questions are welcomed. Asking $50 shipped. First I'll take it, ya know!
