Abstract
A sharpener for a writing instrument includes a receptacle, an entry assembly, and a cutter assembly. The entry assembly is coupled to the receptacle and defines an instrument opening. The entry assembly is configured to receive an end of the writing instrument through the instrument opening along an entry axis. The cutter assembly is configured to revolve about the entry axis in engagement with the entry assembly to sharpen the end of the writing instrument. The cutter assembly is removably engageable with the entry assembly at least by relative translation between the cutter assembly and the receptacle along the entry axis.
