Rigid plastic plate with 1200 Grit and 400 Grit metal plates embedded on opposite sides. At about 6.25 oz., our WoodRiver® 6″ x 2-3/8″ Diamond Stone is a handy size for toolbox, backpack or benchtop. 400-grit side will make short work of small nicks and create the basic edge. The 1200-grit will refine an edge in preparation for final honing or creation of a secondary bevel. This is also an excellent small stone for knives such as pocketknives and kitchen knives.
