Tool having an auto-adjusting handle

A tool, comprising:

• a working member, the working member having a portion providing a plurality of cam surfaces;
• a plurality of expansion members;
• a handle rotatable relative to the working member, the handle having a longitudinally extending chamber in which the portion of the working member is disposed and having a plurality of slots in which the plurality of expansion members are disposed such that, when a torque is applied to the tool, the cam surfaces of the portion 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;
• and
• at least one spring interposed between and in contact with 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.
