A tool and process is provided for pulling a concave portion from a metal panel. The tool and process have a primary use of pulling dents from damaged panels of vehicles. The tool uses four independently hinged legs that are moved up and down by a central control screw and a continuous cable and pulley system. Each of the legs have a plurality of independently acting paired cutting members to hold an individual stud therebetween. The continuous cable also serves the functions of providing a profile of the original shape of the panel and triggering the cutting members to sever the studs. The process involves marking specific points of the dented surface; welding studs to the dented surface at the marked points; inserting the multi-legged tool down over the studs such that each stud is captured and held between a pair of cutting members; turning the screw to cause a lifting of the legs which causes the studs and dented surface to be lifted; lifting each stud upwards until a portion of the dented surface contacts against the cable; triggering the cutting members to sever the stud thereby providing an independent release of the tool from the stud; and finally, pulling up all of the dent until all of the studs are cut.
