Claim:
An apparatus for the manual sharpening of blades of cutting tools, in particular knives and/or scissors, comprising: at least one first sharpening element with at least one sharpening edge, and at least one second sharpening element with at least one sharpening edge, wherein the first sharpening element and the second sharpening element can be or are disposed so as to be partially overlapping, in particular partially in contact with one another, such that in a first state of the apparatus one sharpening edge of the first sharpening element defines a first currently used sharpening edge and one sharpening edge of the second sharpening element defines a second currently used sharpening edge, and the first currently used sharpening edge and second currently used sharpening edge cross one another at a crossing point and form a V-shaped gap with an angle α at the crossing point, into which the blade of the cutting tool to be sharpened is inserted; wherein the first sharpening element and the second sharpening element can be shifted with respect to one another while maintaining the angle α, such that the crossing point is shifted along the first currently used sharpening edge and/or the second currently used sharpening edge; and two or more positionings of the sharpening elements with respect to one another are or can be reversibly fixed; wherein the apparatus comprises a case in which the first sharpening element and the second sharpening element are or can be disposed; such that the first sharpening element and/or the second sharpening element can be shifted relative to the case; and such that two or more positionings of the sharpening elements with respect to one another in the case are or can be reversibly fixed.
