Abstract
A wrench used to tighten and loosen mechanicals on electrical jumper cables without damaging the mechanical. The innovative tool includes a head portion having first and second work surfaces for engaging a mechanical's grip, said first and second work surfaces arranged about an imaginary axis of rotation and substantially parallel to said axis, and a handle secured to the head for allowing manual manipulation of the present invention so as to cause the mechanical grip to rotate. When the innovative wrench head is turned in a predetermined direction, the two work surfaces provide substantial surface-to-surface contact with the mechanical grip being turned, thereby increasing rotational torque while reducing grip deformation and damage.
