Knife sharpening method and system

Abstract

A method and system are disclosed. The system may include a device for sharpening a convex edge on the blade of a knife. The device may include a resilient material and a plurality of abrasive sheets of varying grit values. Each abrasive sheet may be removably attachable to a top of the resilient material. The method may include placing the blade against the abrasive surface at a small angle with a first side of an edge to be sharpened of the blade contacting the abrasive surface and a spine of the blade elevated above the abrasive surface, applying a downward force on the blade causing the edge to be sharpened to compress the resilient abrasive surface, and moving the first side of the edge to be sharpened along the abrasive surface in the direction of the spine.

1 . A method of sharpening a blade to a convex edge on a resilient abrasive surface, comprising placing the blade against the abrasive surface at a small angle with a first side of an edge to be sharpened of the blade contacting the abrasive surface and a spine of the blade elevated above the abrasive surface; 
 applying a downward force on the blade causing the edge to be sharpened to compress the resilient abrasive surface; and    moving the first side of the edge to be sharpened along the abrasive surface in the direction of the spine.    
   
   
       2 . The method of  claim 1 , further comprising placing the blade against the abrasive surface at a small angle with a second side of an edge to be sharpened of the blade contacting the abrasive surface and the spine of the blade elevated above the abrasive surface; 
 applying a downward force on the blade causing the edge to be sharpened to compress the resilient abrasive surface; and    moving the second side of the edge to be sharpened along the abrasive surface in the direction of the spine.    
   
   
       3 . The method of  claim 1 , wherein each step is repeated at least once.  
   
   
       4 . The method of  claim 1 , wherein the abrasive surface includes a first abrasive sheet.  
   
   
       5 . The method of  claim 4 , further including replacing the first abrasive sheet with a second abrasive sheet having a higher grit value.  
   
   
       6 . The method of  claim 1 , further including 
 placing the blade flat against the abrasive surface, and    elevating the spine above the abrasive surface.    
   
   
       7 . A method of removably attaching abrasive sheets of varying grit values to a resilient material for sharpening blades, comprising 
 attaching a first magnetic sheet to the resilient material;    coating one side of a second magnetic sheet with a repositionable adhesive;    attaching the second magnetic sheet to the first magnetic sheet such that the adhesive coated side is opposite the first magnetic sheet; and    removably attaching one of the abrasive sheets to the adhesive coated side of the second magnetic sheet.    
   
   
       8 . The method of  claim 7 , further including 
 removing the one of the abrasive sheets from the second magnetic sheet; and    removably attaching another of the abrasive sheets to the adhesive coated side of the second magnetic sheet.    
   
   
       9 . A method of  claim 7 , further including 
 attaching a leather sheet to a third magnetic sheet;    removing the second magnetic sheet from the first magnetic sheet; and    attaching the third magnet sheet to the first magnetic sheet leaving exposed the leather sheet.    
   
   
       10 . A device for sharpening a blade to a convex edge on a resilient abrasive surface, comprising 
 means for placing the blade against the abrasive surface at a small angle with a first side of an edge to be sharpened of the blade contacting the abrasive surface and a spine of the blade elevated above the abrasive surface;    means for applying a downward force on the blade causing the edge to be sharpened to compress the resilient abrasive surface; and    means for moving the first side of the edge to be sharpened along the abrasive surface in the direction of the spine.
