ABSTRACT:
A flexible knife scabbard has a blade-receiving elongated passage open at one end extending longitudinally therein and has a blade sharpening slot open at both ends extending laterally therethrough and transversely through the elongated passage. Knife blade sharpening insert means including a pair of mating rigid plastic insert members or components are disposed in the elongated passage and each component includes an aperture in registry with the other and with the blade sharpening slot. The insert means further includes a pair of cylindrical ceramic blade sharpening elements or rods, one mounted on each insert component and overlying a portion of the associated aperture. The two rods are disposed in V-shaped arrangement relative to each other and located at (and overlapping) an end of the sharpening apertures in the insert member and the sheath slot. The knife blade slips into the scabbard between the insert members in normal use. In a sharpening operation, the knife blade is inserted through the sharpening slot and through the sharpening apertures and moved reciprocably therein so that the blade edge to be sharpened bears or wipes against the sharpening elements. Such movement is repeated until the desired degree of sharpness is attained.
