Plastic dough scraper
I have various baking tools. One thing that I want but can't find is a plastic dough scraper that has one rounded edge and one straight edge. I looked in several cookware stores but couldn't find it.
I found rounded bowl scrapers, but none with a straight edge. I don't understand why -- isn't it just a piece of flexible plastic?
Does anyone know where I can find one inexpensively (perhaps a hardware store? What should I look for?)? I found many online, but then I have to pay $5 shipping for a $0.50 item... which I am not willing to do.
Another idea that I had was to perhaps cut my own scraper out of a flexible cutting mat. However, I am worried about the cut edge -- is it stable enough not to release various toxins into my dough?
