Weirdly, a dough scraper. It’s not because of the measurement conversions, I don’t think I’d ever noticed them up until now actually. It’s just a really solid dough scraper. I use it for dough, but I’ve also used it for so many other things, like assembling/disassembling furniture, patching holes in the wall, wrapping furniture in a vinyl sheet. Loads of various tasks.

Every so often you find that you need a solid, flat, steel thing, and this comes in handy every single time.
