Abstract
Apparatus for sharpening a cutting tool. In some embodiments, a tool sharpener includes an abrasive medium having an abrasive surface. A stationary tool support guide provides a guide surface that supports a side of the tool during presentation of a cutting edge of the tool against the abrasive surface. A rotatable edge guide has a roller member with a curvilinearly extending outer surface. The roller member is rotatable about an edge guide roller axis to engage, via rolling contact, the cutting edge during the presentation of the cutting edge against the abrasive surface.
Claims27
A tool sharpener for sharpening a cutting tool, the tool sharpener comprising:
- a base structure configured to have an abrasive medium mountable thereto such that the abrasive medium can rotate about an abrasive axis;
- a central body connected to the base structure, the central body being configured to pivot about an edge guide central axis;
- and
- a roller member connected to the central body and being configured to rotate about an edge roller axis when engaged by a cutting edge of the cutting tool,
- wherein the edge roller axis, the edge guide central axis, and the abrasive axis are nominally parallel to one another.
A tool sharpener for sharpening a cutting tool, the tool sharpener comprising:
- a base structure configured to have an abrasive medium mountable thereto;
- a stationary sharpening guide connected to the base structure and configured to engage the cutting tool;
- and
- a roller member connected to the base structure and configured to rotate when engaged by a cutting edge of the cutting tool, the roller member being selectively movable between a retracted position and a deployed position, the roller member being a first distance from the stationary sharpening guide when in the deployed position and a second, greater distance from the stationary sharpening guide when in the retracted position.
A tool sharpener for sharpening a cutting tool, the tool sharpener comprising:
- a base structure comprising a plurality of sharpening stations, each sharpening station comprising:
- an abrasive medium;
- and
- one or more stationary sharpening guides positioned adjacent to an edge of the abrasive medium;
- a rotatable edge guide coupled to the base structure, the rotatable edge guide comprising a roller member that extends along at least a portion of the base structure so as to be simultaneously positioned adjacent to each of the plurality of sharpening stations such that the cutting tool can engage the roller member when using any of the plurality of sharpening stations.
A tool sharpener for sharpening a cutting tool, the tool sharpener comprising:
- a base structure configured to have an abrasive medium mountable thereto;
- a stationary sharpening guide connected to the base structure and configured to engage the cutting tool;
- and
- an edge guide connected to the base structure and having a guide surface that is configured to engage a cutting edge of the cutting tool, the guide surface being selectively movable between a retracted position and a deployed position, the guide surface being a first distance from the stationary sharpening guide when in the deployed position and a second, greater distance from the stationary sharpening guide when in the retracted position.
