The present disclosure presents a grinding apparatus for sharpening an edge tool. The grinding apparatus may comprise a grinding apparatus casing; a cylindrical grindstone and a support element. The cylindrical grindstone is removably attachable to the grinding apparatus casing. The support element is also removably attachable to the grinding apparatus casing for supporting the edge tool to be sharpened during the grinding operation. The support element includes an elongated member, which may be embodied as a cylindrical support bar. The cylindrical support bar may be configured to extend in a direction which is perpendicular to the rotation axis of the cylindrical grindstone, during operation, in such way that a grinding operation is enabled where the edge tool to be sharpened can be sharpened by means of the side surface facing outwardly from the grinding apparatus casing during the grinding operation.

A tool sharpener has first and second guide surfaces to respectively support a cutting tool adjacent first and second abrasive surfaces. A drive assembly moves the first and second abrasive surfaces with respect to the first and second guide surfaces. A control circuit directs a user to place the cutting tool against the first abrasive surface using the first guide surface to sharpen a cutting edge of the tool during a first sharpening operation. The control circuit activates an indicator mechanism at a conclusion of the first sharpening operation to direct the user to perform a second sharpening operation in which the user presents the cutting tool against the second abrasive surface using the second guide surface to sharpen the cutting edge.
