The present invention involves a pencil sharpener that is housed in a pencil cap, having a variable-sized shavings reservoir. The shavings reservoir can be expanded by moving at least one of an internal wall, an external wall, and the sharpener. Contemplated caps comprise any suitable dimension, but preferably have a length that is at least 50%, or at least 75%, that of a corresponding full-length pencil.
