From the manufacturer:
Without control, there is no safety. Only with total control over the work piece can you create precise cuts with total table saw safety. So what is the GRR-RIpper? This is no regular push block. The GRR-Ripper is a precision, guidance, and 3D Push Block System designed to feed wood on a table saw safer than you can with your hands alone and more accurate and more precise than with conventional pushing devices. The results will be better projects with less waste. With it's 3-Directional control, it gives you downward, forward, and lateral pressure on the stock for maximum control and safety.
It’s patented design eliminates the need for bare-hand feeding where the GRR-Ripper serves as a virtual movable blade guard that travels with your hand, rather than a blade guard that is affixed to the back of the table saw, or one that hovers above it. The GRR-Ripper becomes an unyielding barricade between the table saw blade and both of your hands. Maximizing the use of your materials no longer has to compromise your safety. Aside from the safety, you truly get better cuts. Don't take a chance with your safety, get your hands on a GRR-Ripper.
