Abstract: The present invention is an adjustable weight dead blow hammer comprising a hollow head filled with an acceptable fill material. A handle is connected to the head wherein the handle has a hollow chamber that traversers the length of the handle and has an opening into the head. The weight of the hammer head may be adjusted by moving the fill material between the head and the hollow chamber in the handle. Adjustment may be accomplished by a corkscrew device which is disposed within the hollow chamber and having a screw tip at the opening and c screw head on an outside portion of a bottom end of the handle. The corkscrew device within the hollow chamber moves the fill material between the head and the handle. More fill material in the head increases the force of impact, and less fill material in the head decreases the force of impact.
