Apparatus configured to sharpen a blade of a cutting tool. In some embodiments, a sharpener is provided having a housing and a sharpening stage with at least one sharpening element. Each sharpening element is characterized as a plate and has a curvilinearly extending, concave sharpening surface configured to impart a corresponding convex sharpening geometry to a selected side of the blade during a sharpening operation in which a user retracts the blade along a longitudinal drawing axis through the sharpening stage. A pair of intersecting sharpening elements may be provided to form a substantially v-shaped groove for a ripper-type sharpening stage. The sharpening element(s) may be fixed or tiltable with respect to the housing. The sharpening element(s) may further be moveable in a lateral direction to narrow or widen the v-shaped groove and change the convex geometry and edge angle imparted to the blade.

Abrasive block support

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.

Base unit for a powered abrasive belt sharpener

Cartridge for a powered abrasive belt sharpener

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.

Precision adjust sharpener

Embodiments are disclosed for a clasp including a top loop having a catch end, a bottom loop coupled to the top loop, the catch end positioned above the bottom loop at a first side of the clasp, and a depression at a second side of the clasp, opposite the first side, a thinnest part of the second side of the clasp being formed by the depression.

Sharpener with precise adjustment capabilities

A method for manufacturing a custom wearable and/or implantable medical device, such as an orthosis (e.g., an ankle brace, etc.), a prosthesis or the like, includes use of scanning processes. A digital model of a surface may be applied to a digital device model to define a custom digital device model. The digital model and, thus, the custom digital device model may include one or more standard features. The custom digital device model may be used with an automated manufacturing process to make some or all of the custom wearable and/or implantable medical device. In some embodiments, additive manufacturing processes may be used to form a portion or all of the custom wearable and/or implantable medical device.
