There are lots of "odd" tools; specialty tools in various disciplines. When I first read the thread, I had a hard time thinking of any "odd" tools I have in my woodworking shop and the modest collection of hand tools I have that I use for general "mechanicing."
As for the granite table saw tops: I don't think anybody makes them anymore. They were a "thing" for a while about 10-15 years ago, but fell out of favor as they were easy to chip or even crack, and the manufacturers had a high loss rate for tops that cracked before they could get them to the point of sale. Granite tops were known, though for their ability to absorb vibration in a machine. None of my big machines have granite tops; they're all cast iron.
