Abrasive sharpener

Abstract

An abrasive sharpener including a housing having a slotted bottom surface, an abrasive rod pivotally mounted within the slotted bottom surface for movement between a stored position and an extended position, and a first magnet positioned within the slotted bottom surface and arranged to releasably secure the abrasive rod in the stored position. The abrasive sharpener may also include a second magnet positioned within the slotted bottom surface and arranged to releasably secure the abrasive rod in the extended position.

         2 . The abrasive sharpener of  claim 1  wherein the abrasive rod comprises a magnetic material and the abrasive rod is attracted by the first magnet. 
     
     
         3 . The abrasive sharpener of  claim 1  further comprising:
 a mount comprising a first end and a second end, 
 wherein the abrasive rod is secured to the first end and the second end is pivotally mounted within the slotted bottom surface. 
 
     
     
         4 . The abrasive rod of  claim 3  wherein the mount comprises a T shape. 
     
     
         5 . The abrasive sharpener of  claim 3  wherein the mount comprises a magnetic material and the mount is attracted by the first magnet. 
     
     
         6 . The abrasive sharpener of  claim 1  further comprising:
 a second magnet positioned within the slotted bottom surface and arranged to releasably secure the abrasive rod in the extended position. 
 
     
     
         7 . The abrasive sharpener of  claim 6  wherein the abrasive rod comprises a magnetic material and the abrasive rod is attracted by the first magnet and by the second magnet. 
     
     
         8 . The abrasive sharpener of  claim 6  further comprising:
 a mount comprising a first end and a second end, 
 wherein the abrasive rod is secured to the first end and the second end is pivotally mounted within the slotted bottom surface. 
 
     
     
         9 . The abrasive rod of  claim 8  wherein the mount comprises a T shape. 
     
     
         10 . The abrasive sharpener of  claim 8  wherein the mount comprises a magnetic material and the mount is attracted by the first magnet and the second magnet. 
     
     
         11 . An abrasive sharpener comprising:
 a housing comprising a first slotted opening, a second slotted opening and a slotted bottom surface;   a first sharpening element comprising an abrasive rod pivotally mounted within the slotted bottom surface for movement between a stored position and an extended position;   a first magnet positioned within the slotted bottom surface and arranged to releasably secure the first sharpening element in the stored position;   a second sharpening element fixedly secured to an edge of the housing;   a third sharpening element positioned within the first slotted opening; and,   a fourth sharpening element positioned within the second slotted opening.   
     
     
         12 . The abrasive sharpener of  claim 11  wherein the second sharpening element is formed from a ceramic material and comprises a tapered edge. 
     
     
         13 . The abrasive sharpener of  claim 11  wherein the third sharpening element comprises first and second carbide bits arranged to form a V-shape. 
     
     
         14 . The abrasive sharpener of  claim 11  wherein the fourth sharpening element comprises first and second ceramic bits arranged to form a V-shape. 
     
     
         15 . The abrasive sharpener of  claim 11  wherein the abrasive rod comprises a magnetic material and the abrasive rod is attracted by the first magnet. 
     
     
         16 . The abrasive sharpener of  claim 11  wherein the first sharpening element further comprises a mount comprising a first end and a second end, the abrasive rod is secured to the first end and the second end is pivotally mounted within the slotted bottom surface. 
     
     
         17 . The abrasive sharpener of  claim 16  wherein the mount comprises a magnetic material and the mount is attracted by the first magnet. 
     
     
         18 . The abrasive sharpener of  claim 11  further comprising:
 a second magnet positioned within the slotted bottom surface and arranged to releasably secure the abrasive rod in the extended position. 
 
     
     
         19 . The abrasive sharpener of  claim 18  wherein the abrasive rod comprises a magnetic material and the abrasive rod is attracted by the first magnet and by the second magnet. 
     
     
         20 . The abrasive sharpener of  claim 18  wherein the first sharpening element further comprises a mount comprising a first end and a second end, the abrasive rod is secured to the first end and the second end is pivotally mounted within the slotted bottom surface, the mount comprises a magnetic material and the mount is attracted by the first magnet and by the second magnet.
