Mar 06, 2019 The garnet mineral almandine is harder than quartz (Mohs 7.5), but its real virtue is its sharpness, giving it cutting power without scratching wood too deeply. Corundum is the workhorse abrasive of sandpaper. Extremely hard (Mohs 9) and sharp, corundum is also usefully brittle, breaking into sharp fragments that keep on cutting.
