Clamp for a sharpening device used to sharpen a cutting tool

Base member for a sharpening device used to sharpen a cutting tool

Method and apparatus for sharpening a cutting edge of a cutting tool, such as a kitchen knife. In some embodiments, an abrasive assembly has a frame, a handle, and a cartridge that supports a plurality of abrasive members each having an associated abrasive surface. A rod affixes the abrasive assembly to a base assembly to facilitate movement of the abrasive assembly along the cutting edge of the tool responsive to engagement, by a user, of the user handle. Each abrasive member is configured to be moved, by the user, with respect to the handle to present each abrasive surface in turn. In some cases, the cartridge is rotatable about a cartridge axis that may be parallel or non-parallel to a central axis of the rod.

Sharpener with swing arm abrasive assembly

Method and apparatus for sharpening a cutting edge of a cutting tool, such as a kitchen knife. A fixture secures opposing sides of a blade of the cutting tool and includes a main body and hinged first and second clamping jaws each having a clamping end adapted to compressingly engage a respective side of the blade. A guide coupled to the main body has converging support surfaces to contactingly engage a back edge (spine) of the blade opposite the cutting edge to center the blade along a central plane of the fixture. A retraction mechanism establishes a clamping force upon each of the respective sides of the blade via the clamping jaws. Further embodiments include a base assembly adapted to receive the fixture, and a swing arm style abrasive assembly to carry out a sharpening operation upon the cutting edge.

Sharpener with precise adjustment capabilities

Apparatus and method for sharpening a cutting tool, such as a knife. A sharpener includes a first support member, a second support member and a hinge assembly. The first support member supports a first abrasive surface and has at least a first guide at a selected end of the first abrasive surface. The second support member supports a second abrasive surface and has at least a second guide at a selected end of the second abrasive surface. A hinge assembly couples the first and second support member to facilitate movement of the second support member relative to the first support member between a closed position and an open position. In the closed position, the first guide is in facing relation to the second guide and the first abrasive surface is in facing relation to the second abrasive surface.
