I recently met a Jewish scribe in the Old City, and here is a picture of his desk. As you can see there are a couple of cups of coffee remnants as well as various shapes/sizes of pens and edging tools. I would like to stand and watch him work, but so far he hasn't agreed.
I was a little surprised at how messy his desk appeared, but was reminded of my own work bench when I was a jeweler. I think people might have been surprised at how messy my bench was considering that I was handling their priceless family treasures.
