All hands on deck: here is a one-person tool that allows you to free up your hands and legs. BoWrench is the perfect deck-building mate, fully capable of bending several boards simultaneously, including warped boards. It also makes it easier than ever to install tongue-and-groove material.

Just slip on joist, swing the handle, the tool locks in place, holding the board securely and leaving you free to drive nails or screws.
