ABSTRACT:
A leverage assembly is used in combination with an elongated hand tool. The hand tool has a first end adapted for engaging an object and a second end opposite the first end. The leverage assembly includes an adapter bar having first and second ends. A U-bolt attaches the first end of the adapter bar to the second end of the hand tool. A leverage bar engages the second end of the adapter bar. A receptacle is formed with the adapter bar for receiving the leverage bar. The leverage bar, adapter bar, and hand tool cooperate to multiply a force applied by the user to the object to manipulate the object.
