Kraft Tool Co.® ST411PF 0.25" x 3/8" x 0.25" Square Notch Trowel with ProForm® Handle. Professional quality carbon steel notched trowel is precision balanced and ready-to-use. The hardened steel holds its edge even after extended use. Use this notch trowel to spread adhesives and thinset. The 1/4" x 3/8" x 1/4" square-notch is great for spreading thinset for ceramic and quarry tile. 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. Guaranteed No-Turn handle design locks the handle to mounting. Kraft Tool's signature notched trowel with patented ProForm® soft grip handle (US Patent #6,247,204 B1) provides a comfortable grip. The bright orange handle is easy to spot on a jobsite even after use. The contoured shape and enhanced texture ribbing of the handle reduces fatigue and provides a great grip even when wet.
