Usually, in order for a pencil to make it into my collection, it must bear some indication of who made it. For this piece, found at the 2011 Chicago Pen Show, I made an exception.
The awkward clip is marked simply "Pat. 1,325,894," which was issued to Charles Frederick Larsen of Chicago for a cigar lighter on December 23, 1919. View patent here.
Here's a better look at the clip. The top end of the clip has the abrasive surface underneath; the cap has a flint mounted on the side. When the cap is removed, it rubs against the clip and generates a spark.
