Sharpening system having multiple abrasive components

Abstract

An abrasive sharpening system having multiple sharpening stations supported on a base. One of the stations includes ceramic rods having a partial curved outer surface and a pair of flat intersecting surfaces forming a longitudinally extending abrasive edge. The base further supports a flat abrasive stone and a pair of carbide blades for sharpening.

       2 . The system according to  claim 1  wherein said abrasive rod is a ceramic rod.  
   
   
       3 . The system according to  claim 2  wherein said curved wall circumferentially extends for generally 180°.  
   
   
       4 . The system according to  claim 3  wherein flat walls extend equally at 45° to each other from said curved wall.  
   
   
       5 . The system according to  claim 1  wherein said base means includes at least one hole having a plurality of cut-out areas for supporting said abrasive rod angularly upright a plurality of angular positions for a sharpening operation.  
   
   
       6 . The system according to  claim 5  wherein said abrasive means includes a pair of abrasive rods, said at least one hole including a pair of holes having cut-out areas for supporting a lower end portion of said abrasive rods for a sharpening operation.  
   
   
       7 . The system according to  claim 6  wherein said base has a compartment for storing said rods.  
   
   
       8 . The system according to  claim 1  further including a flat abrasive stone mounted on said base means.  
   
   
       9 . The abrasive stone according to  claim 8  wherein said flat stone means has an interrupted upper abrasive surface.  
   
   
       10 . The system according to  claim 9  wherein said interrupted surface is formed by a plurality of holes through said upper abrasive surface.  
   
   
       11 . The system according to  claim 8  wherein said base means includes a V-shaped slot, a pair of opposed carbide cutting blades being supported in said slot forming a V-shaped abrasive surface.  
   
   
       12 . An abrasive sharpener system comprising 
 a base,    a guard being removeably mounted on said base,    a pair of ceramic rods being selectively supported in an angularly upright position to form a first sharpening position,    a flat abrasive stone being supported on said base to form a second sharpening position, and,    said guard acting to cover said flat abrasive stone in a first position and to be carried on said base in a generally upright position to act as a guard.    
   
   
       13 . The system according to  claim 12  wherein said ceramic rods include a cross-sectional configuration having a partially curved outer abrasive surface and a pair of flat intersecting surfaces extending substantially along the length of said rods.  
   
   
       14 . The abrasive sharpener system according to  claim 13  wherein one of said flat surfaces includes a longitudinally extending slot.  
   
   
       15 . A ceramic abrasive rod for being supported on a base for sharpening implements comprising 
 an elongated rod formed of a ceramic abrasive material,    said rod having a cross-sectional shape with a first portion including a curved outer abrasive surface having a semi-cylindrical shape extending substantially along the length of one side of said rod,    said cross-sectional shape further having a second portion including an outer pair of flat intersecting abrasive surfaces extending from said first portion and extending substantially along the length of said rod, and    said pair of intersecting surfaces to form a single longitudinally extending edge.    
   
   
       16 . The abrasive rod according to  claim 15  wherein said curved surface extends for an angle of 180°.  
   
   
       17 . The system according to  claim 12  wherein said base includes a lateral slot for retaining said guard in said generally upright position.  
   
   
       18 . The system according to  claim 12  wherein said guard includes a modified U-shaped cross-section.  
   
   
       19 . An abrasive sharpener system comprising 
 a base having an upper portion and a bottom,    a pair of ceramic rods being selectively supported in an angularly upright position to form a first sharpening position,    a flat abrasive stone being supported on said to form a second sharpening position,    a pair of carbide blades being further supported in slots formed on said base means to form a third sharpening station,    said base having an open compartment deposed on said bottom for receiving said pair of carbide blades for storage.    
   
   
       20 . The system according to  claim 19  wherein said compartment includes securement elements to removeably retain said ceramic rods in said compartment during non-sue.
