Abstract
A plastic sheath for protecting the blades of a pair of scissors being stored or carried comprises two elongated plastic members permanently secured together along a mating seam as by sonic weld to provide a pair of spaced apart side walls and a pair of edge walls which cooperate to define an elongated blade-receiving passage open at one end and extending along the longitudinal axis of the sheath. A blade-sharpening slot extends inwardly from one edge of the sheath transversely to the sheath axis and includes outer and inner interconnected offset slot portions. An elongated abrasive blade sharpening element is stationarily mounted inside the blade passage of the sheath and extends generally longitudinally of the sheath and intersects the blade sharpening slot between offset adjacent ends of the blade sharpening slot portions. In use, the sheath is manually grasped as if it were a handle and a pair of scissors blades are simultaneously received in both slot portions and the blade edges are moved slidably and reciprocably transversely across the sharpening element to effect sharpening. The sheath includes a resilient portion integrally formed in the other edge of the sheath and havin…
