I have written on more than one occasion about my trusty cake whisk. It's essential for mixing oil cakes, waffle batter, etc. I bought it from King Arthur or Vermont Country store years ago, and it is a prized tool. However, until today, I had not seen one for sale anywhere. Lehman's now has it:
Never tried one of those. I use a Viennese spatula for a lot of things, including as a bowl scraper, but I've folded cake batter with one as well. I bought several dozen of them fairly cheaply online.
I use a heavy duty flat whisk for mixing most batters. It serves the same purpose as KAF dough whisk but is easier to clean. Lets see if I can find a picture on Amazon. I'm not sure if this is the same size. If there are two sizes, the smaller is more useful.
