Double-ended wrench with ergonomic handle

A double-ended wrench comprising an elongated handle formed substantially nontwisted extending in a longitudinal direction, a first wrench head positioned at one end of said wrench and a second wrench head positioned at the other end thereof, each said wrench head having an orifice with an imaginary axis of wrench rotation, said first wrench head being positioned relative to said second wrench head whereas the axis of wrench rotation of said first wrench head is substantially perpendicular to the axis of wrench rotation of said second wrench head, said nontwisted elongated handle comprising a first handle portion connecting to said first wrench head, and a second handle portion connecting to said second wrench head, each said handle portion having an elongated cross-sectional shape when viewed in a cross-sectional plane perpendicular to said longitudinal direction, each said cross-sectional shape being elongated in a predetermined direction, said first handle portion being positioned relative to said second handle portion whereas the cross-sectional shape of said first handle portion is elongated in a direction substantially perpendicular to the direction in which the cross-sectional shape of said second handle portion is elongated, and further whereas, the cross-sectional shape of said first handle portion is elongated in a direction substantially perpendicular to the axis of wrench rotation of said first wrench head and substantially parallel to the axis of wrench rotation of said second wrench head, and, the cross-sectional shape of said second handle portion is elongated in a direction substantially perpendicular to the axis of wrench rotation of said second wrench head, and substantially parallel to the axis of wrench rotation of said first wrench head.
