Abstract (en)
[origin: CA3174468A1] The present invention relates to a device (1) for grinding and/or polishing a cutting edge of a cutting tool, preferably a domestic knife, comprising: a handle (2), at least one roller (3) rotatable relative to the handle (2) and at least one disc (4) rotatable relative to the handle (2) for grinding and/or polishing the cutting edge of the cutting tool, wherein the device (1) can be moved over a substrate (U) by exerting force on the handle (2), so that the roller (3) - rotating relative to the handle (2) - rolls on the substrate (U) and the disc (4) can be set in rotation. According to the invention, to further improve the grinding and/or polishing effect of corresponding devices, the disc (4) is rotatable at a different rotational speed/angular velocity to the roller (3).
