The latest technology in concrete floating! The Orange Thunder® with KO-20™ Technology Darby is made with the latest advancement in construction tools. Lightweight, engineered material allows for seamless motions to quickly bring up bleed water to open the surface as it levels and smooths. This 36" tapered darby features curved surface lines to evenly distribute the paste to keep the surface open longer. The blade tapers from 3-1/2" on the heel down to 2-1/2" at the nose allowing for smooth motions especially with one-handed sweeping movements. The square end blade has rounded corners to prevent gouging. KO-20™ material is impact resistant for extended wear. The blade won’t absorb liquids preventing corrosion and rust. Kraft Tool's innovative new darby is reinforced with an aluminum bar to mount the 24" long smooth wood handle. Two hand holes within the handle allows for a variety of hand configurations for pushing, pulling, or one-handed sweeping motions.
