Red | Blue: Long
For the final installment of red and blue lead combination pencils, I present wooden ones that are 8 to 9 inches long:
As for the intended purpose of these pencils, I would say that the Romantic and Rainbow are novelty items. Despacho from Johann Sindel indicates something to do with shipping. And the Hardtmuth and St. Majewski pencils bear the medical caduceus symbol. Why is it useful for medical pencils to be so long? Maybe so that doctors don’t have to bend over quite as far to mark charts that are tied to patients’ beds.
Now for some statistics. I have shown a total of 307 red/blue pencils, not including the mechanical ones. 77% have the red lead on the left, blue on right. — But for U.S.-made ones, only 60% are oriented this way, while 88% of non-U.S. ones are. 74% have left and right sides painted red and blue (or with colored marks left and right). — But for one of these, the leads don’t match the paint! (Can you find it?)
