Yeah - My K&E Mahogany is still a prized possession, even if I can no longer multiply 2x2 on it.

I still have my old K&E from back in the 60's. Remember, it's the C and D scales for multiplication and division. I remember giving a demo to some summer interns before I retired. That had heard of a slide rule, but for the first time, they had a chance to see it being used. They were impressed. Getting that decimal point right is still a killer.
