An apparatus for sharpening the edge of an elongated object includes a housing having an exposed sharpening section with a sharpening element in the sharpening section. The sharpening element is formed from a single abrasive coated sharpening element having a pair of abrasive coated planar comb-like structures formed along opposing sides of the sharpening element. The sharpening element is bent into an X configuration wherein the alternating teeth and slots interdigitate to form the X-shaped configuration and form a sharpening angle between the interdigitating teeth. The sharpening angle has a bisection line with an elongated interrupted sharpening surface. Each of the teeth from one of the comb-like structures is juxtaposed at least one tooth from the other of the structures to form that interrupted sharpening surface with the plurality of abrasive surfaces and a plurality of open areas whereby the edge being sharpened is subjected to repeated alternating contact with the surface of each comb-like structure as the object is moved through the sharpening section.
