Acrylic knife for applying texture to walls. I would like to recognize the superior quality and craftsmanship of this tool. The knife is 18 inches long and is made of clear acrylic. But most importantly, it has a professional hardened aluminum bridge that keeps the blade from bending or deflecting. And the soft threaded handle is compatible with all standard extension rods. If you want to achieve the perfect texture on your walls, the HYDE 09997 is the one for you. Thanks to the perfectly matched flexibility of the blade, this knife leaves no scratches or grooves on the surface.
