Comes with a cover and honing oil. Coarse, Medium, and Fine stones.
Norton's 3 way oil stone sharpening system is a far superior way to sharpen straight edge knives and other cutlery. The base acts as an oil reservoir to soak the stone when it's not in use. The rubber feet on the bottom provide a great, non slip traction system that certainly increases the safety factor. The system includes a dust cover, 1 pint of oil, 1 coarse Crystolon, 1 medium Crystolon, and 1 fine India stone. Replacement stones are available for a very minimal cost.
