Abstract
A hand held sharpener comprises a housing that has three sharpening stones having part cylindrical outer surfaces. A center stone is supported on the housing, and second and third stones are positioned on opposite sides of the center stone with axes of the peripheral surfaces of all the stones generally parallel. The stones axes lie on a plane but the spacing of the axes of a left stone is slightly different from the spacing between the axes of the center stone and the right stone, to form two different sharpening angles where the surfaces of the stones overlap. The configuration permits having a two stage sharpener with three stones that are held in a convenient housing for mounting and use. Both sides of a knife edge are sharpened simultaneously as the knife is drawn across the stones at the overlap region.
