Abstract
A tool has a working member, a plurality of expansion members, and a handle that is rotatable relative to the working member. The handle has a longitudinally extending chamber in which a portion of the working member having cam surfaces is disposed. The handle also has a plurality of slots in which the plurality of expansion members are disposed. When a torque is applied to the tool, the cam surfaces of the working member cooperate with the plurality of expansion members to cause at least a portion of each of the plurality of expansion members to be moved outwardly from the slots to thereby cause the handle to change from having a first cross-sectional shape to a second cross-sectional shape. At least one spring is interposed between each of the plurality of expansion members and the handle for causing the handle to revert back to the first cross-sectional shape upon a removal of the torque as applied to the tool.
