USA autochangers (some flipped a stack so as to play complete Classical Album*) used sapphire even in 1930s. Some UK decks still using steel in 1950. The steel needles are usually single play (not sure if that means both sides). Thorns and bamboo also work and don't so much damage the records.

[* Hence Albums are not 1&2, 3&4 etc but 1&6, 2&5 etc for a 6 disc set. Some were also 12″ rather than common 10″]
