Summary:
The video is about riving knives and how they prevent kickback on table saws.
A riving knife is a safety feature on table saws that helps prevent kickback. Kickback is a dangerous malfunction that can happen when the wood being fed into the saw binds up on the blade and is thrown back towards the operator. Riving knives work by preventing the wood from binding up on the blade. They are thin steel fins that are attached to the arbor assembly and ride directly behind the blade. When the saw is activated, the riving knife sits in the blade's cut and prevents the wood from pinching together. This helps to prevent kickback and keeps the operator safe.
The video also discusses the importance of using other safety features on table saws, such as guards and anti-kickback poles. However, the riving knife is considered to be the most effective safety feature. The video concludes by recommending that viewers never use a table saw without a riving knife.
