The number 1 tool is a push stick for a table saw? I have built cabinets for 20 years and can say, maybe with some authority, that a piece of plywood cut to a rectangle with a notch cut into the long edge is better because it doesn't produce a plastic smell when you inevitably cut into it (1/8th" rips?) and can be had free in any shop. You know all the plywood scraps you keep for later and then debate whether it's environmentally safe to put in the wood stove? Those are the ones!
