This KitchenAid Pastry Blender is a kitchen essential that ensures proper blending for your ingredients with better baking results. Curved, tempered 420 stainless steel wires quickly cut chilled pieces of butter or margarine into flour and other dry ingredients, which is the key to a light, flaky texture. It allows the butter to break up, and with repeated motion, breaks it down into smaller pieces as it mixes through the dough. The pastry blender features a soft, comfortable rubber handle, so pressing the stainless steel wires into the butter or flour mixture is easy. Dishwasher safe for easy cleanup. One year hassle-free replacement and lifetime limited .
