What is a 'dough spatula'? I got a new baking book for Christmas; in it, I found the following sentence:


  [To bake this bread] you will need the following kitchen tools: a digital scale for metric measures, a small scoop for flour, a thermometer, a wide bowl for mixing, a rubber spatula, a dough spatula, and a bench knife


(emphasis mine)

What is a dough spatula and how does it differ from a rubber spatula? What do I look for when I go to the store? Google shows me many products, all of which look entirely different from one another. 

ETA: The first mention I see of it indicates I use it to... clean my hands? "Use a dough spatula to clean the clumps [of flour and water] off your hands and tidy the inside of the bowl"
My first thoughts are this which is actually a scraper but I wouldn't use a metal scraper in a bowl. Being flexible plastic, it flexes and molds itself to the inside of a bowl and allows easy removal of dough.
