"When I began my career as an editorial assistant, I was trained to always use a pencil on proofs—never a pen! I also eschew a digital calendar for a good old-fashioned paper one, and my schedule often changes rapidly and I travel a good deal, making pencils a necessity when I’m away from my desk. I always look for a sharpener I can stick in my bag—which should be easy to find, but it’s not. I like the Duroplast because it contains the shavings within it, which makes a lot of sense if you are often sharpening a pencil on the subway or otherwise on the go.”
