Abstract
The tool has a circular body, and an actuating lever pivotably coupled thereto. The lever, however, has two limbs, joined through a bight, and one of the limbs is fully nested in a recess formed therefor in the body. Consequently, one may grasp the tool about the body, whereat the one limb is nested, without turning the tool on, inadvertently. The other limb extends outwardly from the body, however, and by grasping the tool thereat, and depressing this other limb, the tool is turned on.
