Abstract
A self-sharpening cutting implement, especially scissors, includes two cutting elements which have respective gripping and cutting portions and which are pivotably connected to one another intermediate the gripping and cutting portions for movement relative to one another along a common plane. Each of the cutting portions has a cutting edge and an adjacent planar surface which is situated in the common plane. A layer of abrasive material is applied to one of the planar adjacent surfaces so that, as the cutting edge of the other of the cutting elements slides along this layer, it is sharpened. The layer may be applied by spraying, plating, vapor deposition, vacuum metallizing, sintering, or adhering the abrasive material to the respective planar adjacent surface.
