The Superior Innovations Top Tool is a blue steel edging tool with a 1/2" radius, designed to create clean, consistent rounded edges on formed concrete walls, steps, and slabs. The blue steel blade provides the right combination of stiffness and flexibility for smooth edge work without tearing or dragging the surface cream.
Used during the floating and finishing stage to produce professional-grade radius edges that are durable, aesthetically clean, and safe underfoot. An essential tool for residential and commercial concrete finishers.
