Generations of bakers have relied on handheld tools like this to blend dough for their signature pastries. We updated this kitchen classic with our own design for optimal performance. Slender, curved blades quickly incorporate cold pieces of butter into flour and other dry ingredients - the key to creating pastries with a light, flaky texture. Slender blades are made of durable stainless steel for thorough blending. Curved design of blades promotes rocking motion for optimal efficiency. Nonslip ergonomic handle is designed for maximum comfort and control. Clean blades easily with the included custom scrapers, which store in the handle. Designed and developed exclusively by Williams Sonoma.
