Abstract
A combination trowel and screwdriver is provided wherein the trowel handle houses and removably retains a tool bit drive assembly which houses a plurality of tool bit or screw drives. The user pivots the tool bit drive assembly housing away from the handle to a position extending in the proximate direction from the handle. The user then selects the desired tool bit drive for insertion at the proximate end of the assembly and with the proximate end of the handle screws the screw into a recessed position in a wallboard construction. The user then retracts or repivots the tool bit drive assembly into the handle, and then with the trowel end putties or spreads a wallboard plastic or finishing material over the recessed screw head to finish the wall.
