ABSTRACT:
A lever handle, for a rotary hand tool such as a screwdriver, increases the operating torque of the tool to free a stuck fastener, and includes a generally U-shaped lever member pivotally mounted near the end of the handle, the lever member pivoting from a closed position alongside the handle wherein the tool will be rotated freely and quickly, and wherein a detent releasably holds the lever member in the closed position, to an open position projecting outward from the handle wherein the tool will be operated with increased torque to turn a rotary fastener, with either hand or with both hands, the handle including tapered slots to resiliently expand the lever member for assembly onto the handle.
