Abstract
A combination tool of the plier type which includes a screwdriving blade at one plier jaw point and wrench means presenting a smooth pressing surface at the end of both of the arms connected to the screw-driving blade. The other arm of the plier may be held at a right angle and serves as a lever arm when the tool is used for driving or loosening screws. The wrench means may be a pair of coaxially aligned different sized box wrenches formed unitarily, or a unitarily formed pair of open wrenches opening to the side and may be formed at the ends of each plier arm to provide four different sized wrenches.
