Broken-in and ready for use! Designed and engineered for the professional finisher. Heat-treated golden stainless steel blade is made of a special alloy that will not rust, pit, or stain. The hardened steel holds its edge even after extended use. Each trowel is made with state-of-the-art machinery that grinds the blade to just the right dimension for that perfect feel. Greater flexibility and durability of the blade reduces fatigue when finishing plaster or concrete. The square blade finishes all the way to the corners to complete projects large and small. A high-strength, lightweight cast aluminum mounting stands up to the rigors of plaster and cement work.
