Abstract

The invention concerns a device for sharpening or polishing the blade of a knife, having a slit 2 which is provided in a base plate 1 and which is open towards the outside, for guiding the knife blade, and with processing rods 3, 3' which are pivotably disposed on each side of the slit 2 in opposition to an elastically resilient restoring force and which intersect in the region of the slit 2, wherein the knife blade can be applied to their point of intersection 16. Each processing rod 3, 3' is rigidly connected at its pivot axis 7 to the axis of an eccentric disc 8, 8' which is radially loaded by a spring element 13, 13', such that when the point of intersection 16 is in the region of the outer end of the slit 2 (original position), the spring element 13, 13' engages a location of the eccentric disc 8, 8' whose radial separation from the eccentric axis 7, 7' is smaller than the radial separation of the location where the spring element 3, 3' engages when the point of intersection 16 is in the region of the inner end of the slit 2. Alternatively, an elastically resilient arm is connected to the pivot pin 7 of a processing rod 3, 3' for secure mutual rotation therewith, whose free end is supported on a stop 19, 20, 21 of the base plate 1.
