It’s a scraper. Use it to remove congealed bread dough, hardened chocolate, or any other kind of wet, dry, or sticky stuff from a counter or pastry board -- just sweep the mess directly into the trash before wiping down the surface with soap and water. In a pinch, a bench scraper can even scrape paint or remove ice from car windows…
It’s a straight edge. Use it to level a cup of flour, tighten a log of cookie dough in parchment paper, or (absent an offset spatula) level batter in a sheet pan.
It’s a knife. Use it to trim the edges of rolled-out dough, cut square or oblong cookies, or cut portions of bread dough for rolls.
It’s an extra wide spatula. Use it to loosen and lift pastry, transfer cookies or biscuits, lift a fragile cake layer, or divide and scoop sifted flour from wax paper into a mixing bowl. Or, turn a fragile fish fillet on the grill.
It’s a ruler (if yours is marked in inches). Use it to check the thickness of pie or biscuit dough or a piece of meat, the size of a cookie cutter, or length of a lady finger.`
