The Purpose of a Riving Knife
A riving knife is a safety device that is attached to the blade guard assembly of a table saw. Its primary purpose is to prevent kickback during cutting operations. Kickback occurs when the workpiece gets caught by the rotating blade and is thrown back at high speed towards the operator. This can result in serious injuries.
Unlike a splitter, which is a fixed blade that only keeps the kerf open, a riving knife moves up and down with the blade. This ensures that the knife maintains a close distance to the blade, reducing the risk of kickback regardless of the height or angle of the blade. It also helps prevent the workpiece from getting pinched against the blade, reducing the chance of binding and kickback.
Additionally, a riving knife also helps improve the quality of cuts by reducing tear-out and improving the overall stability of the workpiece. It helps prevent the workpiece from moving or splitting during the cutting process, resulting in cleaner and more accurate cuts.
