Abstract
An apparatus is provided for sharpening, grinding, polishing or honing metal objects which has a motor driven vertically mounted grinding wheel provided with a stream of water which can be recirculated to cool the grinding wheel. The device is provided with an adjustable guard to be mounted at the top of the device which has formed in it several guide means for use in sharpening various tools. A pivotable guard plate can be selectively locked throughout a range of angles with respect to the grinding wheel to provide an appropriate support surface. The guard can be adjusted upwardly and downwardly to accommodate wearing down of the grinding wheel and to adjust the grinding angle.
