Had my first "real" (not-test) use of the Harbor Freight multifunction tool yesterday. My aluminum screen/storm door bit the dust (bad hinge) and had to be removed. It was mounted (into wood) with 17 galvanized 3/4" #8 Phillips pan head screws. As you can probably guess, some of the heads were rusted, and stripped when I tried to unscrew them. I used the multifunction tool to cut slots in the stripped screws, and used a flat blade screwdriver to remove them. The tool was perfect for that job! I used the blade that came with the tool, and got perfect slots for the screwdriver blade. And it cut *fast*.
