Blades are made of heavy-duty steel to exacting specifications. Each blade is designed for longer life and greater performance. Quality and vakue is the trade mark of every ProForm blade.
A combination blade is made from high carbon steel and can provide both floating and finishing functions. By comparison, it is smaller than a float blade and larger than a finish blade. For the floating function, combination blades are run flat, with the leading edge and sides having a slight upward bend so they do not dig into the concrete (similar to the float blade).
For the finishing function, the trailing edge is flat to give a hard, flat finish. The combination blade is used in one direction and cannot be reversed, unlike a finish blade. Some contractors like to use a combination blade, early on in the finishing process after pan floating, to close the small aggregate drag marks that may be left from the floating process.
