Kapoff, from American Pencil Co., has a bottle opener on top —
The metal piece on this Eagle pencil says “Spark-Tip” —
I once thought it was for producing sparks (but why?) or lighting matches, but I couldn’t see how it would work. Now I think it is for testing spark plugs, although I don’t know exactly how.
My favorites of course are these Tape-Measure pencils —
The tapes go to 18 inches.
