Cigar Punch Sharpener With Cylindrical Blade Reshaping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for sharpening cigar punch blades are time-consuming, cumbersome, and often require additional equipment or assistance, failing to effectively reshape the blade for optimal cutting.
Innovation Solution
A cigar punch sharpener comprising a hollow outer-piece with angled cylindrical sharpening walls and a press-fit inner-piece, designed to sharpen and maintain the cylindrical shape of the blade by rotating it within a cylindrical cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual filing with magnifying glass is used to sharpen the punch blade, then the blade can be sharpened, but the process is time-consuming and tedious
Solution Approach 1:
The patent replaces the manual mechanical filing process with an automated rotary sharpening mechanism. The punch blade is rotated against a continuously rotating abrasive wheel, substituting manual filing motions with automated mechanical rotation to achieve sharpening much faster without requiring a magnifying glass or second person
Solution Approach 2:
The device allows the user to sharpen the punch blade independently without requiring assistance from a second person. The automated rotary mechanism performs the sharpening function that previously required manual coordination between multiple people, enabling single-user operation
2Manufacturing precision
If manual filing is used to sharpen the punch blade, then the blade can be sharpened, but additional equipment such as magnifying glass, vice, or second person is required
Solution Approach 1:
The patent combines multiple functions into a single integrated device: the sharpening action, blade rotation, and blade guidance are all performed within one apparatus. The abrasive wheel simultaneously performs the sharpening function that previously required separate filing operations, magnifying glass, and positioning tools
Solution Approach 2:
The automated rotary sharpening mechanism replaces the need for multiple manual tools including magnifying glass, vice, and second person. The mechanical rotation system automatically positions and rotates the blade against the abrasive wheel, eliminating the need for these additional equipment items
3Manufacturing precision
If manual filing is used to sharpen the punch blade, then the blade can be sharpened, but the misshapen blade cannot be effectively reshaped to its circular shape
Solution Approach 1:
The patent employs dynamic rotation of the punch blade against the abrasive wheel to simultaneously sharpen and reshape the blade. The rotational motion allows the blade to be continuously contacted by the abrasive wheel at multiple points, effectively restoring the circular shape while sharpening the edge, whereas static filing cannot achieve this dual function
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device efficiently sharpens and reshapes the cigar punch blade, enhancing its cutting performance without the need for additional tools or assistance, ensuring a precise and efficient cutting action.
Implementation Method 1
The angled cylindrical sharpening wall may be 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

AI summary
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.
