The Norton IM83-O Portable Oil Stone Sharpening System provides a complete sharpening solution. Equipped with three 8" x 3" x 1/2" oilstones (1 Coarse Crystolon, 1 Medium Crystolon, and 1 Fine India) the kit keeps your stones clean, safe, and ready to use. The base acts as a reservoir for your oil and permits continuous submersion of the unused stones. Simply rotate the handle to bring the desired stone into position for sharpening. In addition, the kit also includes a 4.5-oz bottle of oil.

The top cover that encloses the stones and oil reservior has a rubber seal around the lip of the cover so oil will not leak out of the tool box when you are on the move.  When the bottom compartment is removed, the blue reservior for the oil has it's rubber feet, just like other professional sharpeners from Norton.  The gray bottom compartment is large enough for other tools or knives.

The unique carrying case allows the user to sharpen whenever needed -- at home or on the go. Sturdy metal latches secure the cover and storage case where small tools and knives can be stored.
