This is the question I posed to some friends last week, to which I got really quizzical looks. I'm on the Sur La Table mailing list and they sent me an email about such blade, and how can one resist? Just look at the picture below and read the description.
You voted this as one of your favorites: Continuously beat, scrape and fold ingredients in your electric mixer in about half the time with the BeaterBlade. The flexible, high-quality, food-grade plastic eliminates hand-scraping bowls, unmixed flour on bowl’s edges and batter build-up on the blades. Patented ‘wing-system’ design acts like a wiper blade that continuously scrapes sides and bottom of the bowl while mixing.
Ingredients are thoroughly included and mixed, ensuring foolproof baking preparation. BeaterBlade scrapes even the dimple at the bottom of the bowl. Perfect for cakes, cookies, frosting, bread, compound butters, meatloaf, pie fillings, mashed potatoes, gum paste and more. Fits either 5-qt., 6-qt. or 7-qt. mixers. BeaterBlade doubles as a spatula. Made in the USA.
What really got me is that it even scrapes the dimple at the bottom of the bowl. At $24.95, and in these economic times, I can't really justify spending the money on such an object. Plus, it just sounds so pompous...
...but it would have come in handy for the coconut cake I made last week. Pictures below!
