A bench grinder is a stone wheel spun by a motor. The whole assembly is fastened to a workbench. A grinding wheel has many uses, including sharpening knives. The grinding wheel produces a sharper blade than many other methods. The process of sharpening a knife on the grinding wheel produces sparks, so proper safety gear is necessary. The task should take you three to five minutes.
