You can find anything on the web.

You know those "rods" that you use to wind a scroll -- the ones that the parchment is attached to, and that you roll and unroll? Today someone asked me -- in the context of a Torah scroll specifically -- what those are called. I didn't know, but I had a browser.

Elapsed time until I had the answer: 51 seconds. :-)

( Oh, you wanted to know too? )

I still don't know what it's called in the more general case, though. Fortunately, the more specific the question, the easier it is to find an answer. :-)
