Well I used to teach infants and everyday I had this job. I always sharpened all the pencils in the pencil pots, especially if it was handwriting . I had classes of 30 children , if I only did it once a day over one week that was 150 pencils, so over the year ..imagine. Sometimes I would hate it , a blunt sharpener and it took for ever. So I thought this had to be the challenge, a pencil sharpener , shavings and a nice sharp pencil. Not my usual drawing subject but took the challenge, in pencil.
