In some embodiments, the sharpener has a handle with opposing first and second ends, an outer grip surface, and a guide surface adjacent the first end extending at a selected angle with respect to a central axis. A first abrasive rod is adapted to extend from the first end of the handle in a selected direction parallel to the central axis and having a first outer abrasive surface with a first abrasiveness level, the first outer abrasive surface extending at a first non-orthogonal angle with respect to the guide surface. A second abrasive rod is adapted to extend from the first end of the handle in the selected direction and having a second outer abrasive surface with a different, second abrasiveness level. The second outer abrasive surface extends at a different, second non-orthogonal angle with respect to the guide surface.
