ABSTRACT:
A sharpening apparatus includes a base and a pair of thin elongated cylindrical sharpening rods of the type that can be made of a ceramic material which is loaded with a strong abrasive. The rods are storable in a compartment provided by the base in side-by-side relationship and in such position are accesible for sharpening of a pointed object such as a hunting arrowhead or a dart. The rods are movable to a second position with respect to the base still in side-by-side relationship but with ends extended beyond the base for the sharpening of the ends of objects having a more complicated configuration such as fishing hooks. The rods are mountable in a third position with respect to the base in which they are held in the base in adjacent angular relationship with each other and in acute relationship to the base. In this position the rods can be used to sharpen objects such as knife blades.
