A blade scabbard including a safety lock which functions to prevent accidental or inadvertent withdrawal of a blade from a fully inserted position within the scabbard housing. The safety lock operates automatically in response to insertion of a blade into the scabbard and is preferably associated with blade sharpening mechanism which is also responsive to movement of a blade into and out of the scabbard housing. The sharpening mechanism is preferably inactive during blade insertion and active during blade withdrawal. Manually operable release means is provided to enable release of the lock for blade withdrawal purposes, and it is necessary to operate the release means while simultaneously withdrawing the blade from the scabbard. The safety lock is fully released after the blade has been withdrawn a distance from the fully inserted position and operation of the release means can then be terminated without hindering further withdrawal of the blade. Blade restraining means coacts with the blade to prevent withdrawal when the safety lock is fully operative, and that restraining means may be pivotally mounted on the scabbard housing, together with the sharpening mechanism, to be pivoted into and out of the operative position.

[ I claim:] [1.] A blade scabbard including,a hollow housing for containing a blade,an access opening at an end of the housing through which said blade can be moved longitudinally to be inserted into or withdrawn from said housing,blade sharpening means positioned to be engageable by a cutting edge of said blade when said blade is located within said housing, means connecting said sharpening means to said housing to permit relative movement between an active position at which said sharpening means is operative to sharpen said cutting edge and an inactive position at which said sharpening means is not so operative, said sharpening means being responsive to movement of said blade relative to said housing so as to be thereby moved towards said inactive position when the blade is being inserted into the housing and moved towards said active position when the blade is being withdrawn from the housing,restraining means connected to said housing and being operative to coact with said blade or a member associated therewith when the blade is at a predetermined position of insertion within said housing so as to thereby prevent withdrawal of said blade from the housing,said restraining means being responsive to movement of said sharpening means into said active position so as to be thereby automatically rendered inoperative,and manual release means which is operable to render said restraining means inoperative.
