| 摘要 |
The object of the invention relates to a device for sharpening knives, comprising a freely rotatably mounted grinding element (6) consisting of two truncated cones turned against each other. In known devices of this kind, one side of the knife blade (17) remains unground at the free end and handle end of the blade. This can be avoided, if the grinding element (6) can turn around one end (11) of its axle (10) in such a way that the axle forms an angle with respect to the sharpening direction of the knife, which angle is smaller or larger than 90 DEG in the end positions of the axle.
