Method and apparatus for knife and blade sharpening

The method of claim 3 wherein the elongated object is a knife having a blade face, and locating the guide member so that when the blade face contacts the guide member the center line of the blade established from its edge to the center of its thickness at its back is positioned generally at the bisection line of the included angle of the abrasive coated interdigitating surfaces.

An apparatus for sharpening the edge of an elongated object comprising a housing having an exposed sharpening section, a sharpening element in said sharpening section, said sharpening element being formed from a single abrasive coated sharpening element having a pair of abrasive coated planer rigidly stationarily mounted comb-like structures formed along opposing sides of said sharpening element, said comb-like structures consisting of alternating teeth and slots, said sharpening element being bent into an X shape configuration with a base wherein the comb-like structures interdigitate to form the X shape configuration and form a sharpening angle between said interdigitating teeth, said angle having a bisection line, elongated interrupted sharpening surfaces being at the vertex of said x-shape, and each of said teeth from one of said abrasive coated comb-like structures being juxtaposed at least one tooth from the other of said structures to form said elongated interrupted sharpening surfaces with a 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 said sharpening section.
