How A Table Saw Blade Guard Assembly Works

Protecting fingers and preventing kickback

The standard table saw blade guard assembly includes a pivoting, clear-plastic blade guard, which deflects flying wood chips and reduces the chance that fingers will slip accidentally into the blade. The guard is connected to a thin piece of metal known as the splitter or riving knife. Attached directly in line with the blade, the splitter keeps the saw cut—or kerf-open. Without such a device, the kerf may close during a cut, binding the blade and throwing the workpiece back toward the operator with great force. Kickback can also result if a work-piece jams between the blade and the rip fence. Further protection from kickback is provided by a metal finger (or fingers) called an anti-kickback pawl, which normally rides on the surface of the workpiece. In the event of kickback, the finger digs in, preventing the workpiece from flying back.
