The Curta is a hand-held mechanical calculator designed by Curt Herzstark. It is known for its extremely compact design: a small cylinder that fits in the palm of the hand.

More precise then a slide rule, but much more expensive, I'm sure. My old plastic rule that I used in college, cost around $10.

They were expensive when new.

I got to hold and use one once, friend of a friend had it. It felt so satisfying in my hands.

!flashlight@lemmy.world has metal cylinders of about that size with knurling too.
