A double-ended wrench is described comprising a first wrench head connected to one end of an elongated handle and a second wrench head connected to the other end thereof. Each wrench head has an orifice formed f or engagement with various fasteners, and each orifice has an imaginary central axis of wrench rotation. The first wrench head is positioned relative to the second wrench head whereas the axis of wrench rotation of the first wrench head is substantially perpendicular to the axis of wrench rotation of the second wrench head. The elongated handle is formed comprising a first handle portio n connecting to the first wrench head, and a second handle portion connecting to the second wrench head, and a third handle portion located between the first and second handle portions. Each handle portion has a location at which ther e is a defined cross-sectional thickness when the wrench is viewed from an end view thereof. The third handle portion has a cross-sectional thickness substantially greater than a cross-sectional thickness of each of the first and second handle portions.
