All of them will have a few
And we do use specialist slide rules when I worked as a mechnical engineer for working out loads and Ixx Iyy values of H beams, bolt loads etc on flanges. That was in 1998 and I can't see things changing much because it was a very quick easy way of getting the data you required. I still have my metric imperial converter for doing pressure pipe work for ASME codes.
Military use them for working out ranges, Artillery use them for firing solutions in case the electronics go tits up.
Slide rules arn't as dead as you think.
