A blade sharpening device comprises a clamp for holding a blade in a fixed position relative to the device, an elongate slide member having a lower end adapted for sliding movement on a flat surface and an elongate support arm having a first end mechanically connected to the slide member. The elongate support arm extends at a fixed angle relative to the slide member and has a second end with the clamp provided thereon.

A device for grinding and/or polishing a cutting edge of a cutting tool. The device includes a handle, at least one roller rotatable relative to the handle, and at least one disc that is rotatable relative to the handle for grinding and/or polishing the cutting edge of the cutting tool. The device can be moved over a substrate by exerting force on the handle so that the roller, which is rotating relative to the handle, rolls on the substrate and the disc can be set in rotation. The disc may be rotatable at a different rotational speed/angular velocity to the roller.

A sharpening device, components thereof, and associated methods. The sharpening device includes a sharpening assembly and a housing. The sharpening assembly is selectively receivable in the housing in a stowed configuration and supportable by the housing in an operational configuration to support the sharpening assembly for sharpening a blade. The sharpening assembly can include first and second arms having respective abrasive sharpening surfaces pivotable away from each other about a pivot connection.

A sharpening sheath, adapted to receive a knife to be sharpened or stored, comprising a cavity for receiving a blade, an access opening at one end of the cavity, the sheath comprising, preferably in the vicinity of the access opening an upper part provided with a guiding device for the back of the blade and a lower part comprising a sharpening device on which the cutting edge of the blade is intended to be applied when inserting or extracting the blade in the sheath, characterized in that the guide device comprises a V-shaped groove and in that the sharpening device comprises two sharpening elements arranged in a V-shape opposite the groove of the guide device, the sharpening device being mounted so as to be movable relative to the guide device and being returned by return means in the direction of the guide device.

A housing interiorly forms an upper chamber and a lower chamber. An upper opening in the front face of the housing provides access to the upper chamber. A lower opening in the front face provides access to the lower chamber. An upper cover is removably positionable in the upper opening. A lower cover is removably positionable in the lower opening. A razor head with razor blades is removably received by an upper holder and by a lower holder. An ultrasonic motor in the upper chamber vibrates sanitizing fluid. A sharpening assembly contacts and sharpens the razors of the razor head in the lower chamber. A direct current motor in the lower chamber drives the sharpening assembly.

A multi-rod hand-held sharpener. In some embodiments, the sharpener has a handle with opposing first and second ends, an outer grip surface, and a guide surface adjacent the first end extending at a selected angle with respect to a central axis. A first abrasive rod is adapted to extend from the first end of the handle in a selected direction parallel to the central axis and having a first outer abrasive surface with a first abrasiveness level, the first outer abrasive surface extending at a first non-orthogonal angle with respect to the guide surface. A second abrasive rod is adapted to extend from the first end of the handle in the selected direction and having a second outer abrasive surface with a different, second abrasiveness level. The second outer abrasive surface extends at a different, second non-orthogonal angle with respect to the guide surface.

The invention relates to hand tools of knife sharpening, especially for sharpening of kitchen knifes, namely relates to angle guides for knife sharpening. This angle guide has a removably attachable body that is put on a sharpening rod through a hole going through the body, which has the ability to move back and forth on the rod. The body has guiding cutouts for the blade of a knife that allow to maintain the desired angle against the sharpening rod during the sharpening procedure. At least one pair of cutouts with inclined narrowing cavities are formed in the body on its opposing sides in opposing directions, which allows to alternate between the sides of the blade during the sharpening process and in this way much less burr is produced.
