A combination blade, crafted from high-carbon steel, offers dual functionality, serving both as a floating and finishing tool. Compared to a float blade, it's smaller, yet larger than a finish blade. When employed for floating, these blades operate flat, with a slight upward bend along the leading edge and sides to prevent concrete digging.
For finishing tasks, the trailing edge remains flat, resulting in a smooth, solid finish. Unlike finish blades, combination blades are unidirectional and cannot be reversed. Some contractors prefer using combination blades early in the finishing phase, following pan floating, to eliminate minor aggregate drag marks left during the floating process
