Abstract
A sharpening tool comprising a handle, a housing portion extending from the handle, and a rotatable disk mounted within the housing. The disk can include multiple sharpening stations arranged along its perimeter. A user-actuated knob, rotatably coupled to the housing, enables selective rotation of the disk in order to position a desired sharpening station in an exposed orientation. In some embodiments, the knob rotates the disk in an opposite direction, with their axes of rotation laterally offset. A positioning mechanism, such as a magnet or detent, may bias the disk toward discrete positions, and a locking mechanism may prevent unintended rotation. Each sharpening station can include a first abrasive contact element to sharpen an edge of a blade and a second smoother contact element to support or guide the blade.

A sharpening tool comprising:
- a handle;
- a housing portion extending from a front end of the handle;
- a disk rotatably mounted within the housing portion;
- at least two sharpening stations positioned along a perimeter of the disk;
- a knob rotatably coupled to the housing portion and extending from a side thereof;
- wherein
- rotation of the knob causes the disk to rotate within the housing portion;
- at any given time, one of the sharpening stations is positioned in an exposed orientation such that it is accessible for sharpening an edge of a blade;
- and
- a different sharpening station can be made accessible by rotating the knob to reposition the disk.
A method to sharpen an edge of a blade, the method comprising:
- providing a sharpening tool comprising:
- a handle;
- a housing portion extending from a front end of the handle;
- a disk rotatably mounted within the housing portion;
- at least two sharpening stations positioned along a perimeter of the disk;
- a knob rotatably coupled to the housing portion and extending from a side thereof, wherein rotating the knob causes the disk to rotate within the housing portion;
- rotating the knob until a suitable sharpening station is exposed such that the suitable sharpening station is accessible for sharpening the edge of the blade;
- drawing the blade through a first and second contact elements of the suitable sharpening station to sharpen the edge of the blade, wherein the first contact element configured to sharpen the edge of the blade and the second contact element configured to guide and/or support the blade during sharpening.
