The present invention is a pencil sharpener or the like such as a makeup pen. It uses two handles similar to a pair of pliers. In one configuration, pressing the two handles advances oblique sharp tip blades which cut through the wood and core of a pencil. The result is that the pencil is sharpened in one press of the handles. The second configuration has even number of blades. With two blades, it requires the handles to be pressed a second time after manually rotating the pencil 90 degrees. With 4 blades, each two opposing blades cut through the pencil in half the pressing interval. With 6 blades, each two opposing blades cut through the pencil in one third the pressing internal, and so on.

The present invention provides a sharpening completion detection mechanism that does not apply a heavy load to a core tip, and especially proposes a mechanism that moves a pencil in an ejection direction immediately when the sharpening completion detection mechanism detects completion of sharpening to mitigate damage to the core. Specifically, a pencil sharpener according to the present invention includes: a slide unit that translates in pencil insertion and pencil ejection directions; a pencil biasing means supported by the slide unit; a slide locking means that locks a translation position of the slide unit upon the slide unit translating in the insertion direction; and a slide unit unlocking means that releases the lock for the translation position of the slide unit upon the sharpening completion detection means detecting a fully sharpened state of the pencil, and includes slide unit ejecting means that biases the slide unit in the ejection direction with energy stored by movement of the slide unit to a lock position.

A crayon cutter having a housing and a cutter positioned in the housing. The housing defines a first opening configured to receive a crayon and a second opening. The cutter is configured for actuation to cut a portion of the crayon off of the remainder of the crayon. The cutter is positioned in the housing so that the portion of the crayon passes through the second opening after it is cut off of the remainder of the crayon.
