A system for stopping a spinning table saw blade is comprised of a pin assembly disposed adjacent to a saw blade assembly for stopping a spinning saw blade. A receiving block is disposed on a side of the saw blade opposing the pin assembly for receiving the tip of the pin assembly. A driving assembly is coupled to the pin assembly for driving the pin assembly into the spinning saw blade into the receiving block. Finally, a sensing assembly is coupled to at least one of the saw blade assembly and the driving assembly for sensing encroachment of a user's hand in a pre-defined zone. In use, upon sensing a user's hand the sensing assembly signals the driving assembly to stop the spinning saw blade by driving the pin assembly through the saw blade and into the receiving block.
