Huh! And light weight. Actually makes sense too. The things you learn here... Incidentally, reminded me, I'd heard opuntia spines (https://en.wikipedia.org/wiki/Opuntia https://en.wikipedia.org/wiki/Opuntia AKA prickly pear) were used for the needles waaaay back. Can't find a ref but heard it on a TV program. FYI. Edit: can't play this but see if this is informative https://www.youtube.com/watch?v=wxuPDTlIofY https://www.youtube.com/watch?v=wxuPDTlIofY "Making Phonograph Needles from a Cactus"
