Sharpening apparatus

Abstract

A sharpening apparatus. A cylindrical body having a first cylindrical body end and a second cylindrical body end, the cylindrical body defining a bore extending from the first cylindrical body end to the second cylindrical body end. A cylindrical shaft comprising a first shaft end and a shaft second, the first shaft end defining a first shaft bore and the second shaft end side defining a second end bore. A first tubular member adjacent the first shaft end and the first cylinder body side and a second tubular member adjacent the second shaft end and the second cylinder body side. A first wheel comprising a first wheel stem, wherein the first wheel stem engages the first shaft bore defined by the cylindrical shaft. A second wheel comprising a second wheel stem, wherein the second wheel stem engages the second shaft bore defined by the cylindrical shaft.

What is claimed is: 
     
         1 . A sharpening apparatus comprising:
 a cylindrical body having a first cylindrical body end and a second cylindrical body end, the cylindrical body defining a bore extending from the first cylindrical body end to the second cylindrical body end;   a cylindrical shaft having a first shaft end and a shaft second, the first shaft end defining a first shaft bore and the second shaft end side defining a second end bore;   a first tubular member residing adjacent the first shaft end and the first cylinder body side;   a second tubular bearing residing adjacent the second shaft end and the second cylinder body side;   a first wheel comprising a first wheel stem, wherein the first wheel stem engages the first shaft bore defined by the cylindrical shaft; and   a second wheel comprising a second wheel stem, wherein the second wheel stem engages the second shaft bore defined by the cylindrical shaft and wherein the second wheel comprises a first surface defining a spiral raceway along an outer surface of the second wheel.   
     
     
         2 . The sharpening apparatus of  claim 1  wherein the cylindrical body comprises a beech wood, walnut wood, or oak wood treated surface. 
     
     
         3 . The sharpening apparatus of  claim 1  wherein the first shaft bore comprises at least one beveled edge. 
     
     
         4 . The sharpening apparatus of  claim 1 , wherein the bore extending from the first cylindrical body end to the second cylindrical body end comprises a central bore. 
     
     
         5 . The sharpening apparatus of  claim 1 , wherein the cylindrical body includes a bore comprising a unitary diameter. 
     
     
         6 . The sharpening apparatus of  claim 1 , wherein the cylindrical shaft comprises a stainless-steel shaft. 
     
     
         7 . The sharpening apparatus of  claim 1  wherein an outer diameter of the cylindrical body is substantially equivalent to an outer diameter of the first wheel. 
     
     
         8 . The sharpening apparatus of  claim 1  wherein the first shaft bore extends only along a portion of a length of the cylindrical shaft 
     
     
         9 . The sharpening apparatus of  claim 1  wherein the first wheel comprises a first surface, this first surface comprising an abrasive diamond coated layer. 
     
     
         10 . The sharpening apparatus of  claim 9  wherein the diamond layer comprises at least a grit size of D91. 
     
     
         11 . The sharpening apparatus of  claim 1  wherein the first wheel comprises stainless steel. 
     
     
         12 . The sharpening apparatus of  claim 1  wherein the first wheel rotates simultaneously with the second wheel. 
     
     
         13 . The sharpening apparatus of  claim 1  wherein the first wheel comprises a concave cutout along a radially extending portion of the first wheel. 
     
     
         14 . The sharpening apparatus of  claim 13  further comprising an elastic member placed within the concave cutout. 
     
     
         15 . The sharpening apparatus of  claim 1  wherein the spiral raceway is milled into the second surface of the second wheel at approximately a 90-degree angle. 
     
     
         16 . The sharpening apparatus of  claim 1  wherein the first wheel comprises a second surface wherein a circular recess is milled along the second surface of the first wheel. 
     
     
         17 . The sharpening apparatus of  claim 16  wherein the circular recess milled along the second surface of the first wheel comprises a first recess diameter. 
     
     
         18 . The sharpening apparatus of  claim 17  where the first tubular member residing between the first shaft end and the first cylinder body end comprises a flange having a first flange diameter;
 wherein the first recess diameter is substantially equivalent to the first flange diameter. 
 
     
     
         19 . The sharpening apparatus of  claim 1 , wherein the first wheel stem removably engages the first shaft bore defined by the cylindrical shaft. 
     
     
         20 . The sharpening apparatus of  claim 1 , wherein the removable engagement of the first wheel stem and the first shaft bore is a threaded engagement.
