Wüsthof Key Chain Knife Sharpener

No, it's not a joke; this is a real, two-stage knife sharpener small enough to fit on a key chain. Measuring just 3" x 1", and weighing a mere 1 oz. this sharpener has two stages. One stage employs carbide rods that remove a small amount of steel to apply a new edge, the other stage features ceramic rods that realign the edge for regular maintenance between sharpening, or for fine honing. Rubber feet keep this little sharpener stable while in use.
