 the first stem of the first body end of the body frictionally engages a first stem recess defined by the first magnetic portion.   
     
     
         5 . The sharpening apparatus of  claim 4 , further comprising a cylindrical bearing, the cylindrical bearing configured to operably couple the first stem of the first body to the first stem recess defined by the first magnetic portion. 
     
     
         6 . The sharpening apparatus of  claim 1 , wherein
 the first metallic wheel comprises a first protrusion and a second protrusion, wherein the first protrusion and the second protrusion extend away from a first surface of the first metallic wheel.   
     
     
         7 . The sharpening apparatus of  claim 6 , wherein
 the first magnetic portion defines a first protrusion receiving recess and a second protrusion receiving recess,   a first magnet disposed in the first protrusion receiving recess,   a second magnet disposed in the second protrusion receiving recess,   wherein the first protrusion receiving recess of the first magnetic portion is configured to operatively receive the first protrusion of the first metallic wheel; and   wherein the second protrusion receiving recess of the first magnetic portion is configured to operatively receive the second protrusion of the first metallic wheel.   
     
     
         8 . The sharpening apparatus of  claim 1 ,
 wherein the first wheel comprises a second surface, the second surface comprises a grinding surface.   
     
     
         9 . The sharpening apparatus of  claim 1 , wherein
 the first wheel comprises a second surface, the second surface comprises a polishing surface.   
     
     
         10 . The sharpening apparatus of  claim 1  wherein
 the first wheel comprises a second surface, the second surface comprises an abrasive diamond coated layer. 
 
     
     
         11 . The sharpening apparatus of  claim 1 , wherein
 the first wheel comprises a second surface, wherein this second surface comprises a ceramics surface.   
     
     
         12 . The sharpening apparatus of  claim 1 , wherein
 the first wheel comprises a second surface, wherein this second surface comprises a Corundum surface.   
     
     
         13 . The sharpening apparatus of  claim 1 ,
 wherein the body comprises a hexagonal body.   
     
     
         14 . The sharpening apparatus of  claim 1  wherein
 an outer diameter of the body is different than an outer diameter of the first wheel. 
 
     
     
         15 . The sharpening apparatus of  claim 1  wherein
 the first wheel comprises a stainless steel wheel. 
 
     
     
         16 . The sharpening apparatus of  claim 1  wherein
 the first magnetic portion comprises a concave recess along a radially extending portion of the first wheel. 
 
     
     
         17 . The sharpening apparatus of  claim 16  further comprising
 an elastic member placed within the concave recess. 
 
     
     
         18 . The sharpening apparatus of  claim 1  wherein
 the first wheel comprises a spiral raceway provided along a second surface of the first wheel. 
 
     
     
         19 . The sharpening apparatus of  claim 18  wherein
 the spiral raceway is milled into the second surface of the first wheel at approximately a 90-degree angle.
