Böker diamond sharpening pencil

Small and lightweight, the pen-sized pocket sharpening rod, set with industrial diamonds, combines both a tapered and cylindrical side with a flattened contact surface and a fishhook sharpening groove in the smallest space. The tapered side can be used for serrated edges, the cylindrical side for all straight edges of knives with steel blades. The unused side of the pole retracts into the aluminum handle and is secured with a cap nut. When not in use, the rod can be almost completely sunk into the handle and the sharpener can be attached to clothing with a spring steel clip. The first and lightest choice for professional sharpening while backpacking.
