Am I the only person
to have been brought up with a Keuffel & Esser ivory covered mahogany
rule? Also, what was the name of the manufacturer who made a bamboo core
rule?
K&E made a bamboo one, too. (At least mine looks like bamboo -- it
certainly isn't mahogany).
I was told that bamboo has a low coefficient of linear expansion, which is
why they used it.
