I don’t think I’ve ever cut a piece of drywall in my life, but if I ever do, I will surely want this amazing tool. The Maximum Drywall Axe is a combination of a retractable blade along with a measuring tape, so that you can measure the length of the piece you need to cut ahead of time, lock the tape measure in place, and then precisely cut the length of the drywall while keeping the exact measurement at all times.
