ABSTRACT:
A device particularly suited for sharpening broadhead arrows and having sharpening surfaces which are curved in the direction the broadhead travels as it is sharpened. In a preferred embodiment, the sharpener comprises two sharpening surfaces to sharpen broadhead arrows and a third cylindrical sharpening surface which can be used to sharpen other discrete cutting elements. Each broadhead sharpening surface is formed as two sections which are curved about an axis perpendicular to the direction of travel of the arrow blades so that only one line of contact is formed between a blade and its respective sharpening section, resulting in even sharpening along all the points on a blade.
