A medical cutting device for creating thin slices, has a device body, a cover, a working section which rigidly adjoins a connecting section, and a recess on the top side, which is enclosed by a delimiting ridge. The cover comprises a counterpart to the connecting section adjoined by a pressure section which is positioned opposite the recess at a distance da, and therefore a guide slot extending between the working section and the pressure section remains free for a cutting blade. The distance of the guide slot to the bottom surface of the recess, which is defined by the distance da, defines the thickness, which can be achieved, of a slice to be created. The cutting blade is disposed within the guide slot and is rigidly connected to a rotatable shaft extending perpendicularly to the plane of the guide slot and extends through a recess in the cover.
