The push stick you use with your table saw is an integral part of the safety system that helps keep you out of harm’s way. As such, don’t take the lowly push stick for granted. There are numerous push stick styles and designs, some shop-made and others store-bought, but in my view, not all push sticks offer the same level of safety.
Pictured is the style push stick I’ve relied on for years. It’s made from 3/4″ hardwood plywood and is about a 12″ long and 6″ wide (from the bottom to top of the handle). I keep a 3/8″ heel near the back on the bottom to hook the wood that’s being pushed along. I don’t apply any sort of finish so it grips well. I route a 1/4″ round-over everywhere except the bottom where it contacts the wood when in use. The grip or handle is angled forward slightly so my wrist is in a comfortable position.
