Made of stainless steel (as not to disturb your sourdough's beautiful bacteria) this is one of my favorite Sourdough tools. Ideal for getting goo off your cutting boards 

Works wonderfully to separate your dough without smashing it or ruining your knives. Wooden cutting board? This is perfect for scraping off the crusties left behind after a day of baking sourdough bread. Complete with measurements in case you're into that kind of thing.
