Abstract: A sheath for a knife with a dead blade such as a hunting knife, a Bowie knife or the like comprises a quiver, a suspender attached to the quiver and serving to push the sheath onto a body belt, and an annular retainer pivotted to the suspender, capable of being pushed over the handle of the knife and serving to secure the knife in the quiver. The suspender of the sheath in the proximity of its lower end has an edged recess extending across the width of the suspender and a tongue adjacent thereto. The tongue is bevelled and defines the lower end of the suspender. The quiver of the sheath at the rear side has an edged U-shaped bridge integral with the quiver. The bridge is arrested with its web in the recess of the suspender. The suspender has an elongate hole extending from its one narrow side to the other narrow side. The rear side wall of said hole is made a resilient arm by a transverse slot. The annular holder is clipped into a semi-cylindrical bearing disposed at the suspender.
