Abstract
Abstract A metal leveler tool includes a body having a handle portion and a housing. A chuck is received by the body through the housing for linear movement between two limit positions. A movable handle is coupled to the chuck and mounted by the body for pivotal movement about a fulcrum. A machine screw is supported by the chuck to be threadedly received through a workpiece within an area of a dent upon movement of the chuck to one limit position followed by pivotal movement of the movable handle. The housing of the body is supported by an anvil which is supported by the workpiece over the dent. Pivotal movement of the movable handle in the other direction followed by reverse movement of the chuck to the second limit position acts to draw the dented area of the workpiece toward the anvil.
