Cigar punch sharpener

Abstract

A cigar punch sharpener with an outer-piece and an inner-piece, each having a generally cylindrical shape. The outer-piece includes an angled cylindrical sharpening wall for sharpening a cigar punch cutting blade while the blade is rotated about the angled cylindrical sharpening wall. A rounded edge located on at least one end of the inner-piece and the angled cylindrical sharpening wall of the outer-piece form a cylindrical cavity tapering to an endpoint. The inner-piece is configured to accept and guide the cigar punch cutting blade to the angled cylindrical sharpening wall as the blade is inserted into the cylindrical cavity. The inner-piece is also configured to maintain or reshape the generally cylindrical shape of the cigar punch cutting blade as the blade is worked on the cigar punch sharpener by twisting the cigar punch within the cylindrical cavity.

What is claimed is: 
     
         1 . A cigar punch sharpener, comprising: 
 A hollow outer-piece having a generally cylindrical shape and first and second ends comprising:    an outer surface;   an inner surface;    an angled cylindrical sharpening wall located on at least one of the first and second ends of the outer-piece wherein the angled cylindrical sharpening wall is configured to sharpen an outer edge of a cigar punch cutting blade of generally cylindrical shape while the blade is rotated about the angled cylindrical sharpening wall;   an inner-piece having a generally cylindrical shape and first and second ends and comprising: 
 an inner-piece surface configured to be firmly attached to the inner surface of the outer-piece; 
 an inner-piece face with a rounded face edge located on at least one of the first or second ends of the inner-piece; 
 wherein the inner-piece and the angled cylindrical sharpening wall of the outer-piece form a cylindrical cavity tapering to an endpoint where the inner-piece and outer-piece meet; 
 wherein the inner-piece is configured to accept and guide the cigar punch cutting blade to the angled cylindrical sharpening wall as the blade is inserted into cylindrical cavity and to maintain or reshape the generally cylindrical shape of the cigar punch cutting blade as the blade is worked on the cigar punch sharpener by twisting the cigar punch within the cylindrical cavity. 
   
     
     
         2 . The cigar punch sharpener of  claim 1 , wherein the angled cylindrical sharpening wall is knurled. 
     
     
         3 . The cigar punch sharpener of  claim 2 , wherein the outer-surface of the outer-piece is knurled. 
     
     
         4 . The cigar punch sharpener of  claim 3 , wherein the angled cylindrical sharpening wall is angled relative to the inner-surface of the outer-portion by between 14° and 16°. 
     
     
         5 . The cigar punch sharpener of  claim 4 , wherein: 
 the inner-surface of the outer-piece has an outer-piece first portion, a outer-piece second portion of relatively larger interior diameter, and an outer-piece radial step located where the outer-piece first portion and outer-piece second portion meet;    the inner-piece has an inner-piece first portion, a relatively larger diameter inner-piece second portion, and an inner-piece radial step located where the inner-piece first portion and inner-piece second portion meet; and   wherein the inner-piece and outer-piece are configured to be press-fit together by forcibly pushing the inner-piece first portion through the outer-piece second portion and continuing through the outer-piece first portion until the inner-piece step meets the outer-piece step.    
     
     
         6 . The cigar punch sharpener of  claim 5 , wherein the inner-piece first portion has an inner-piece knurled portion configured to collapse and deform when the inner-piece is press fit into the outer-piece. 
     
     
         7 . The cigar punch sharpener of  claim 6 , further comprising: 
 a first cylindrical cavity formed by the first end of the inner-piece and the first end of the outer-piece;   a second cylindrical cavity formed by the second end of the inner-piece and the second end of the outer-piece;   wherein the first and second cylindrical cavities are configured to accept relatively different diameter cigar punch cutting blades of generally cylindrical shape.   
     
     
         8 . The cigar punch sharpener of  claim 7 , wherein the first cylindrical cavity is configured to accept a cigar punch cutting blade approximately 7 mm in diameter. 
     
     
         9 . The cigar punch sharpener of  claim 8 , wherein the second cylindrical cavity is configured to accept a cigar punch cutting blade approximately 9 mm in diameter. 
     
     
         10 . The cigar punch sharpener of  claim 9 , wherein the outer-piece and inner-piece are made of aluminum.
