A grinding device (2) is inserted in the synthetic resin housing (1) of the knife sharpener, this grinding device consisting of a supporting unit (3) with two resiliently designed supporting arms (6, 7) for two grinding wheels (8, 9). In the installed condition, the grinding wheels (8, 9) extend in sections and with a mutual spacing through slots (17, 18) in the housing wall (16) into a trough-like indentation (19) of the housing (1) accessible from the top. The two grinding wheels (8, 9) form, in the region of the indentation (19), by a partial overlap (20) with their peripheral surfaces (21, 22) a honing angle ( alpha ) which is infinitely variable within a range of 40 DEG -50 DEG .
