type into which different screw driver blades or tips can be inserted hexagonally shaped rods 34 and 86 would also fit into a standard motorized screw driver rods 34 and 86 could also be magnetized so that they are better retained by such handles fig1 and 11 shows a tool 90 having handles 91 and 92 the ends of jaws 93 and 94 adjacent end 95 have grooves similar to those discussed above that extend between cavity 98 and end 95 jaws 93 and 94 are provided with blade like protrusions 96 and 97 respectively that extend toward each other when jaws 93 and 94 are closed on a screw these protrusions cooperate to form a blade that can extend into the slot of the screw this causes the tool to grip the screw even more tightly whereas the tool of fig1 and 11 is especially adapted for the insertion of slot head screws it could also insert phillips head screws by placing the head slightly in front of protrusions 96 and 97 then the grooved jaws 93 and 94 would secure the screw moreover the shapes of protrusions could be modified so that the tool accomodates phillips head screws the above described modified locking pliers provide a superior means for securely holding and installing wood screws machine screws and even bolts the screws are held straight and rigid and do not wobble or slip during installation the following observations have been made while using the above described tool a with this new tool one need not concentrate on keeping.
