  • Hand tool for gripping objects
    Patent number: 5857723
    Abstract: A spark plug wire puller is described which is actuated by a user squeezing a trigger biased against a handle of the tool which causes two jaw members to come together at gripping ends thereof to squeeze a wire or boot. As the user squeezes the trigger and pulls on the tool, the jaws grip the wire or boot and remove it from the spark plug. The invention is advantageous because it does not rely on a scissors action and it grips the boot in such a way so as not to damage it during the removal process.
