Abstract: A knife scabbard including a hollow housing which is adapted to receive the blade of a knife and which at least partially contains a pivoted carrier member having a blade sharpening device mounted thereon. A latch device is also pivotally connected to the housing and overlies part of the carrier member and in particular that part which carries the sharpening device so as to bear on the upper edge of a knife blade which engages the sharpening device. The pivotal axis of the carrier member is located adjacent a top wall of the housing and at an inner end of the carrier member which is divided so that a knife blade can pass therethrough and intersect the pivot axis. Mounting means for the pivoted inner end of the carrier member comprises a part of the housing and a portion of a spring which also serves to urge the carrier member about the pivot axis towards the housing top wall.
