A cookery tool, used for kneading and cutting dough for bread/doughnuts/etc. I recommend, of course, printing it in a food-safe material and/or sealing the blade with resin
If you don't have a 3D printer but you'd really like one of these please send me a DM and we can arrange for me to produce one for you, or check out my Numonday store:
