The shell has an exit opening, an access opening with a mounting socket, and a medially located lateral control slot through which the control tab extends. The retention sleeve has a collet, compressed by the compression spring and uncompressed by the control tab. The disk holder has a body with a retention ridge and a pair of lugs extending from each end to retain a marking disk. One marking disk has a circular periphery and the other marking disk has a toothed periphery. The cap is mounted upon either end. The sharpener includes a blade with a sharpened edge secured to a body with an upper surface, a peripheral surface with a shoulder, waist, and hip, and a lower surface.
