Retractable abrasive sharpener and carrying case

Abstract

A hand held retractable abrasive sharpener having a rod formed with a tapered end portion and a partially cylindrical opposite end portion. A part of the partially cylindrical opposition end portion is flat. A slot is formed in the rod. Substantially all of the outer surfaces include layers of the rod have an abrasive material. The rod is carried in a carrying case for tansport and storage in a locked relationship and being capable of being released and withdrawn for sharpening with carrying case serving as a holder.

1 . A hand held abrasive sharpener comprising 
 a rod having a first end section,    said end section having a tapered, generally conical configuration;    an opposite end section having at least a partially cylindrical configuration;    said first and opposite end sections having an abrasive surface for sharpening edges;    a carrying case for carrying said rod in a secured or release configuration, said carrying case having locking means for releasably securing said rod to said carrying case for transport and for selectively releasing said rod to be extended from said carrying case at a projected position for a sharpening operation.    
   
   
       2 . The sharpener according to  claim 1  wherein said rod includes a longitudinal open slot for sharpening other edges.  
   
   
       3 . The sharpener according to  claim 2  wherein said opposite section of said rod includes a flat abrasive surface.  
   
   
       4 . The sharpener according to  claim 1  wherein said locking means releasably locks said rod at said projected position to said carrying case.  
   
   
       5 . The sharpener according to  claim 4  wherein said carrying case acts as a holder for a sharpening operation in said locked projected position of said rod.  
   
   
       6 . The sharpener according to  claim 4  wherein said locking means has a cylindrical hollow cap having internal threads, said carrying case having an open end section for receiving said rod, said open end section having external threads for engaging said internal threads of said cap, said cap being moveable on said external threads from a position locking said rod to said carrying case to a position releasing said rod for movement relative to said carrying case.  
   
   
       7 . The sharpener according to  claim 6  wherein said open end section includes open end slots, said slots being compressible to cause said carrying case to grip said rod in said locking position.  
   
   
       8 . In an abrasive sharpener comprising 
 an elongated rod having a first end section formed with an outer surface in a tapered shape,    said rod having an opposite end section formed with an outer surface in a partially cylindrical shape, a section of said opposite end section having a longitudinally extending flat surface,    a slot formed in said opposite end section, and    said outer surface of said tapered section, said outer surface of said partially cylindrical section, said flat surface and said slot all having an abrasive outer surface.    
   
   
       9 . A hand held abrasive sharpener comprising 
 a rod having a first end section,    said end section having a tapered, generally conical configuration;    an opposite end section having at least a partially cylindrical configuration;    said first and opposite end sections having an abrasive surface for sharpening edges; and    a carrying case for carrying said rod.    
   
   
       10 . The hand held abrasive sharpener according to  claim 9  wherein said carrying case has means for releasably securing said rod to said carrying case for transport and for selectively releasing said rod to be extended from said carrying case at a projected position for a sharpening operation.  
   
   
       11 . In an abrasive sharpener comprising 
 an elongated rod having a first end section formed with an outer surface in a tapered shape,    said rod having an opposite end section formed with an outer surface in a partially cylindrical shape, a section of said opposite end section having a longitudinally extending flat surface, and    said outer surface of said tapered section, said outer surface of said partially cylindrical section and said flat surface all having an abrasive outer surface.
