The invention relates to an apparatus ( 10 ) for the manual sharpening of blades of cutting tools, in particular knives and/or scissors, comprising at least one first sharpening element ( 40 ) with at least one sharpening edge ( 42, 43 ), and at least one second sharpening element ( 41 ) with at least one sharpening edge ( 44, 45 ), wherein the first sharpening element ( 40 ) and the second sharpening element ( 41 ) 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 ( 53 ) of the apparatus ( 10 ) one sharpening edge ( 42, 43 ) of the first sharpening element ( 40 ) defines a first currently used sharpening edge ( 49 ) and one sharpening edge ( 44, 45 ) of the second sharpening element ( 41 ) defines a second currently used sharpening edge ( 50 ), and the first currently used sharpening edge ( 49 ) and second currently used sharpening edge ( 50 ) cross one another at a crossing point ( 51 ) and form a V-shaped gap ( 52 ) with an angle alpha at the crossing point ( 51 ), into which the blade of the cutting tool to be sharpened is inserted. According to the invention it is provided that the first sharpening element ( 40 ) and the second sharpening element ( 41 ) can be shifted with respect to one another while maintaining the angle, such that the crossing point ( 51 ) is shifted along the first currently used sharpening edge ( 49 ) and/or the second currently used sharpening edge ( 50 ), and that two or more positionings of the sharpening elements ( 40, 41 ) with respect to one another are or can be reversibly fixed.
