Book 3 — Cleanly Pencil Sharpener
Reading edition
Pencils may be pointed without spreading the dust from them by the use of the device shown in the illustration. A piece of emery paper is fixed to one side of the cover of the box. By turning over the cover with a handle, after a pencil has been pointed, the dust may be dropped into the box and removed from time to time.—Sidney Block, Detroit, Mich.
