A cutlery sharpener is disclosed for conditioning a cutlery edge. The cutlery sharpener comprises a sharpening shaft extending between a proximal end and a distal end and defining a sharpening surface for engaging the cutlery edge. A line of symmetry extends through the proximal end and the distal end of the sharpening shaft. A handle extends between a proximal end and a distal end and defining a handle surface for engaging a hand. A non-line of symmetry extends through the proximal end and the distal end of the handle. A couple links the proximal end of the sharpening shaft with the proximal end of the handle. The non-line of symmetry maintains a thumb and a plurality of fingers of the hand in a safe orientation and safe distance from the cutlery edge during displacement of the handle relative to the cutlery edge and engagement between the cutlery edge and the sharpening shaft.

A media-bearing polisher and restorer removes surface and subsurface contaminants from a vehicle, household or other surface. The media-bearing polisher and restorer comprises an ovoid body with a planar bottom. The body comprises a resilient or rigid material and one or more flutes for receiving one or more user fingers. A permeable elastic medium is removably attached to the planar bottom of the body, which absorbs and extracts contaminants from the surface. A variety of media can be used with the media-bearing polisher and restorer.

A small and portable apparatus for sharpening the blades of a pair of scissors is provided according to the invention. The scissors sharpener comprises a main body; a vertically-oriented, stationary sharpening steel having opposed surfaces that is securely attached to the main body; a pivotable sharpening steel that rotates with respect to the main body; and a U-shaped return spring positioned between the main body and the pivotable sharpening steel. A user inserts a pair of scissors so that the inside surfaces of the two blades abut the opposed surfaces of the stationary sharpening steel for stable alignment, and closes the blades against the pivotable sharpening steel to cause it to travel along the blade cutting edges to sharpen them. When the scissors blades are disengaged from the scissors sharpening apparatus, the return spring will bias the pivotable sharpening steel back to its standby position.
