The hardened steel holds its edge even after extended use. Use this notch trowel to spread adhesives and thinset.

This 11" x 4-1/2" steel trowel blade is notched on two sides and straight on two sides. A high-strength, lightweight cast aluminum mounting stands up to the rigors of tile work. Compression fit stainless steel rivets attach the mounting to the blade. An oversized toe rivet provides extra strength when applying pressure during finish work.
