Blade sharpening device

Abstract

The present invention provides a blade sharpening device designed for sharpening a blade for a uniform sharpening of the edge thereof. Generally, the blade sharpening device includes a base, a guide, a carriage, and a blade holder. The base has a guide movable relative to the base. In one embodiment, the base includes a material that receives an impression of a blade defining a blade contour. A blade holder is attached to the base for securing the blade while being sharpened. The carriage includes a means for interacting with the material of the guide or the carriage to define a sharpening path substantially aligning with the blade contour. The carriage has an abrasive surface for sharpening the blade. In operation, the guide and carriage direct the movement of the abrasive surface along the contour of the blade for a uniform sharpening of the edge thereof.

1 . A blade sharpening device, comprising:
 a base, said base includes a material that receives an impression of a blade defining a blade contour;   a blade holder attached to the base for securing the blade while being sharpened;   a guide rotatably movable relative to the base;   a carriage containing a means for interacting with the material of the guide to define a sharpening path substantially aligning with the blade contour, said carriage having an abrasive surface for sharpening the blade;   whereby said guide and carriage direct the movement of the abrasive surface along the contour of the blade for a uniform sharpening of the edge thereof.   
     
     
         2 . The blade sharpening device of  claim 1 , further comprising:
 means for sharpening along a tangent line of the blade relative to the abrasive surface.   
     
     
         3 . The blade sharpening device of  claim 1 , further comprising:
 means for adjusting degree of material removed from a blade.   
     
     
         4 . The blade sharpening device of  claim 1 , further comprising:
