Using ceramic sharpening tools allows you to get a fine edge on your knife with less chance of it becoming nicked or damaged.
Each 2"x8" stone comes packaged in a rigid polymer storage case complete with non-skid rubber feet for tabletop use. This stone should be used dry without lubricants or oils. To clean, wash with fresh water and scrub metal particles from the stones with a plastic scouring pad and abrasive powered cleanser.
Four 5" alumina ceramic sticks (2-medium grade for sharpening and 2-fine grade for finishing) angled in two V-shapes on a wooden base provide the proper sharpening angle for your knife. Sticks store inside the base for convenient carrying.
